May I ask how to make the device support Simplified Chinese font display

You can if your device hardware supports PSram and has a large 16Mb flash to hold the font file.
Upload a Truetype font, for example chinese.ttf and use the text_font parameter to select it:

{"page":4,"id":1,"obj":"btn","x":5,"y":35,"w":90,"h":90,"radius":0,"value_str":"\uE769","text":"\n欢迎","toggle":true,"value_ofs_y":-24, "text_font": "chinese36"}
{"page":4,"id":250,"obj":"label","x":240,"y":150,"w":240,"align":"center","template":"祝您有个美好的一天！", "text_font": "chinese24"}
