There is no complete example. I created a new one. The following example is working on my computer. % Maybe you need to explicitly specify the font name through the “tf” parameter. % Just replace “adobesongstdlight” with your own font. %%%%%% \definefallbackfamily [mainface][rm][adobesongstd][tf={adobesongstdlight},sl={features:slanted},preset=range:chinese] \definefontfamily [mainface][rm][libertinusserif] \setupbodyfont [mainface] \mainlanguage[cn] \setupscript[hanzi] \sl 李信真是太好玩了，还带保送的 some word others %%%%%%% Because there are many hanzi characters in Chinese, it is scattered in different ranges, so the scope of Chinese characters is defined. You can define it by \definefontfamilypreset. These ranges are in： https://wiki.contextgarden.net/List_of_Unicode_blocks.
