Hi - Could I ask you to confirm which version of the game you downloaded?
谢谢你下载这个百合游戏！只有1.12以上的版本有中文翻译。要是想要用中文版的话，请下载"draw-no-more-win-linux.zip"还是 "draw-no-more-osx.zip"。
Only versions >= 1.12 have the Chinese translation. The "DrawNoMore-<os>-jam-submission.zip" files are minimal versions that do not have the Chinese translation bundled with the game. Please be sure to download the versions titled "draw-no-more-<operating system>.zip".
然后选择“PREF”和再选择“Chinese（simplified）”就应该能弄成中文版。
Afterward, press "PREF" on the main menu and select "Chinese (simplified)"
