Clearly, this can&#8217;t be done with normal 3&#215;3 cubes unless you use many of them. Considering that people have used <a href=\"https:\/\/www.guinnessworldrecords.com\/world-records\/473622-largest-rubiks-cube-mosaic-image\">109,000 cubes to create a giant mosaic<\/a>, you can obviously write Chinese characters.<\/p>\n<p>But this is cheating. I want to use one face of a cube for each character. That means we need at least two cubes, since we can use two faces on each cube for a total of four characters.<\/p>\n<p>Thus, we enter the rabbit hole: How small can Chinese characters be while remaining legible? How many pixels do you need to write characters? How big Rubik\u2019s Cubes do you need?<\/p>\n<p>Naturally, I&#8217;m going to focus on the Chinese side of the challenge. Solving big Rubik&#8217;s Cubes is not on-topic for Hacking Chinese, but it&#8217;s not terribly hard if you know how to solve smaller cubes.<\/p>\n<p>So, let&#8217;s dive in. First, how big a cube do we need?<br \/>\n<a name=\"how-small-can-a-chinese-character-be-while-still-being-legible\"><\/a><\/p>\n<h3 id=\"how-small-can-a-chinese-character-be-while-still-being-legible\">How small can a Chinese character be while still being legible?<\/h3>\n<p>This might seem like a simple question, but it&#8217;s not.<\/p>\n<p>For example, how good is your eyesight? If you see twice as well as I do, you can see a character half the size.<\/p>\n<p>I can compensate for my poor eyesight, though! If I have a camera, I can zoom and read the character anyway.<\/p>\n<p>This is neither surprising nor interesting, so we need to approach the question from a different angle. This is not about absolute size.<br \/>\n<a name=\"whats-the-smallest-resolution-needed-to-display-chinese-text\"><\/a><\/p>\n<h3 id=\"whats-the-smallest-resolution-needed-to-display-chinese-text\">What&#8217;s the smallest resolution needed to display Chinese text?<\/h3>\n<p>Another way to approach the issue is to think in terms of resolution, or pixels of a fixed area, such as that of a character on a page or screen.<\/p>\n<p>In short, how many pixels do you need to write Chinese text while keeping it legible?<\/p>\n<p>A primitive way to figure out the minimum resolution is to simply check the most complex character and see how many horizontal and vertical pixels we need.<br \/>\n<a name=\"different-chinese-characters-require-different-resolutions\"><\/a><\/p>\n<h3 id=\"different-chinese-characters-require-different-resolutions\">Different Chinese characters require different resolutions<\/h3>\n<p>But which characters are we writing?<\/p>\n<p>We only need one pixel vertically and two horizontally to write \u4e00 (y\u012b), &#8220;one&#8221;, but to write \ud869\udea5 (zh\u00e9), &#8220;verbose; talkative&#8221;, we need at least 22 pixels vertically and 16 horizontally if we want to show all strokes. In case the fonts you have installed can&#8217;t display that character, here&#8217;s an image for you:<\/p>\n<p><a href=\"https:\/\/www.hackingchinese.com\/wp-content\/uploads\/2025\/10\/ta4.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-20784 size-medium\" src=\"https:\/\/www.hackingchinese.com\/wp-content\/uploads\/2025\/10\/ta4-295x300.png\" alt=\"\" width=\"295\" height=\"300\" srcset=\"https:\/\/www.hackingchinese.com\/wp-content\/uploads\/2025\/10\/ta4-295x300.png 295w, https:\/\/www.hackingchinese.com\/wp-content\/uploads\/2025\/10\/ta4.png 594w\" sizes=\"auto, (max-width: 295px) 100vw, 295px\" \/><\/a><\/p>\n<p>This seems a bit unfair, though, considering that \ud869\udea5 is not used in normal texts. This introduces subjective judgment about which characters we include and which to skip.<\/p>\n<p>It should also be clear that simplified characters can be displayed in a legible manner with lower resolution than traditional characters,<a class=\"c1\">\u00a0<\/a><a class=\"c1\" href=\"https:\/\/www.hackingchinese.com\/are-simplified-characters-really-simpler-to-learn\/\">even if traditional characters are probably easier to read in general<\/a>.<\/p>\n<p>But let&#8217;s say, just for the sake of argument, that we want to write the Chinese title of this website: \u63ed\u5bc6\u4e2d\u6587.<\/p>\n<p>What\u2019s the lowest number of pixels we need?<br \/>\n<a name=\"chinese-characters-are-not-read-in-isolation\"><\/a><\/p>\n<h3 id=\"chinese-characters-are-not-read-in-isolation\">Chinese characters are not read in isolation<\/h3>\n<p>This question can\u2019t be answered either; deeper into the rabbit hole we go!<\/p>\n<p>So far, we have just looked at individual characters, but just like in all languages, reading in Chinese is not primarily about decoding individual glyphs.<\/p>\n<p>The question is not if you can read a single character out of context, but if you can read it in context. And there&#8217;s almost always context.<\/p>\n<p>Building meaning from the smallest parts, such as individual characters, is called bottom-up processing and is a necessary part of reading comprehension. But there\u2019s far more to reading comprehension than that!<br \/>\n<a name=\"its-possible-to-read-a-chinese-character-without-even-seeing-it\"><\/a><\/p>\n<h3 id=\"its-possible-to-read-a-chinese-character-without-even-seeing-it\">It&#8217;s possible to read a Chinese character without even seeing it<\/h3>\n<p>In most cases,\u00a0\u00a0top-down processing matters more than bottom-up processing. When you read a text, you also use what you already know and understand to comprehend what you&#8217;re reading.<\/p>\n<p>I discussed this in detail for listening comprehension in these two articles, but the same can be applied to reading as well:<\/p>\n<ul>\n<li><a class=\"c1\" href=\"https:\/\/www.hackingchinese.com\/beyond-ting-bu-dong-part-2-from-sound-to-meaning-in-mandarin\/\">Beyond t\u012bng bu d\u01d2ng, part 2: From sound to meaning in Mandarin<\/a><\/li>\n<li><a class=\"c1\" href=\"https:\/\/www.hackingchinese.com\/beyond-ting-bu-dong-part-3-using-what-you-already-know-to-aid-listening-comprehension-in-chinese\/\">Beyond t\u012bng bu d\u01d2ng, part 3: Using what you already know to aid listening comprehension in Chinese<\/a><\/li>\n<\/ul>\n<p>For example, if you show this to someone who has a basic reading ability in Chinese, they will know what the third character is:<\/p>\n<p>\u6253\u55b7\ufffd\/\u6253\u5674\ufffd<\/p>\n<p>You don&#8217;t even need to see the character to know that it&#8217;s \u568f, because \u6253\u55b7\u568f\/\u6253\u5674\u568f (d\u01ce p\u0113nt\u00ec), &#8220;to sneeze&#8221;, is the only common phrase that begins like this.<\/p>\n<p>In that sense, you need 0x0 pixels, or no information, to &#8220;read&#8221; that character.<\/p>\n<p>This was not a cherry-picked example! The principle can be applied anywhere, to varying degrees, but it does assume that the reader is literate in Chinese. If you don&#8217;t know that there is only one common phrase that fits, you won&#8217;t be able to read the character.<\/p>\n<blockquote class=\"wp-embedded-content\" data-secret=\"L8pZHvMsKH\"><p><a href=\"https:\/\/www.hackingchinese.com\/beyond-ting-bu-dong-part-3-using-what-you-already-know-to-aid-listening-comprehension-in-chinese\/\">Beyond t\u012bng bu d\u01d2ng, part 3: Using what you already know to aid listening comprehension in Chinese<\/a><\/p><\/blockquote>\n<p><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"&#8220;Beyond t\u012bng bu d\u01d2ng, part 3: Using what you already know to aid listening comprehension in Chinese&#8221; &#8212; Hacking Chinese\" src=\"https:\/\/www.hackingchinese.com\/beyond-ting-bu-dong-part-3-using-what-you-already-know-to-aid-listening-comprehension-in-chinese\/embed\/#?secret=g8bvHPDq9W#?secret=L8pZHvMsKH\" data-secret=\"L8pZHvMsKH\" width=\"500\" height=\"282\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe><\/p>\n<p>&nbsp;<\/p>\n<p><a name=\"chinese-pixel-fonts-and-lcd-displays\"><\/a><\/p>\n<h3 id=\"chinese-pixel-fonts-and-lcd-displays\">Chinese pixel fonts and LCD displays<\/h3>\n<p>This is not just a topic of interest to people like me who happen to find both Chinese characters and Rubik&#8217;s Cubes interesting.

If you want to learn this, the progression looks something like this:<\/p>\n<ol>\n<li><a href=\"https:\/\/www.youtube.com\/watch?v=7Ron6MN45LY\">Learn to solve a 3&#215;3<\/a> (anyone can do this in 30 minutes with a good tutorial)<\/li>\n<li><a href=\"https:\/\/www.youtube.com\/watch?v=KWOZHbDdOeo\">Learn to solve a 4&#215;4<\/a> (considerably easier than step 1)<\/li>\n<li><a href=\"https:\/\/www.youtube.com\/watch?v=qfdmRCRGLDA\">Learn to solve any NxN<\/a> (much easier than either of the above steps)<\/li>\n<\/ol>\n<p>I&#8217;ve linked to tutorials on YouTube above, but here I will focus on a few key points relevant to my project that you don&#8217;t need to know how to solve the cube to follow.<\/p>\n<p>To begin with, you have to choose colours wisely. While centre pieces can be moved around more or less at will (as long as you don\u2019t care about the other four faces, which we don\u2019t), this is not true for edge and corner pieces.<\/p>\n<p>For example, since white and yellow are opposite faces on the solved cube, there are no edge or corner pieces that are white and yellow. This means that some high-contrast versions are unavailable. It\u2019s impossible to use white and yellow as background colours on two adjacent faces, which is why I use white and green.<\/p>\n<p>Finally, it\u2019s worth noting that it matters if the order of the cube is an even or odd number. With even numbered cubes, like 10&#215;10, the colour of each centre is not fixed, and you don\u2019t have a central axis for writing characters (the middle line goes between two pixels).<\/p>\n<p>On a cube of uneven order, the centre pieces are fixed, which means the colours I chose above would be impossible to achieve on a 7&#215;7 or 9&#215;9. On the other hand, you have a central axis, so writing something like \u4e2d is pretty easy. On an 8&#215;8, the skewering vertical stroke would have to be either twice as thick or off-centre.<br \/>\n<a name=\"lo-and-behold-written-using-rubiks-cubes\"><\/a><\/p>\n<h3 id=\"lo-and-behold-written-using-rubiks-cubes\">Lo and behold! \u63ed\u5bc6\u4e2d\u6587 written using Rubik&#8217;s Cubes<\/h3>\n<p>Now that we have a design, the only remaining challenge is to execute it on actual Rubik&#8217;s Cubes. Hacking Chinese is not about solving big Rubik&#8217;s Cubes, so I won\u2019t go into details here.<\/p>\n<p>To put it very briefly, though, if you can solve big cubes (and if you can\u2019t, you might want to learn that first), you already know commutators well. These can be used to manipulate the centres of a solved cube to show what you want. You can do the same thing for edges and corners, and voil\u00e0:<\/p>\n<p><a href=\"https:\/\/www.hackingchinese.com\/wp-content\/uploads\/2025\/10\/2024-11-19-22.30.27-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-20750\" src=\"https:\/\/www.hackingchinese.com\/wp-content\/uploads\/2025\/10\/2024-11-19-22.30.27-1024x768.jpg\" alt=\"\" width=\"1024\" height=\"768\" srcset=\"https:\/\/www.hackingchinese.com\/wp-content\/uploads\/2025\/10\/2024-11-19-22.30.27-1024x768.jpg 1024w, https:\/\/www.hackingchinese.com\/wp-content\/uploads\/2025\/10\/2024-11-19-22.30.27-300x225.jpg 300w, https:\/\/www.hackingchinese.com\/wp-content\/uploads\/2025\/10\/2024-11-19-22.30.27-768x576.jpg 768w, https:\/\/www.hackingchinese.com\/wp-content\/uploads\/2025\/10\/2024-11-19-22.30.27-1536x1152.jpg 1536w, https:\/\/www.hackingchinese.com\/wp-content\/uploads\/2025\/10\/2024-11-19-22.30.27-2048x1536.jpg 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/p>\n<p>That\u2019s it, Hacking Chinese, written on a 10&#215;10 and a 7&#215;7 Rubik&#8217;s Cube.
