Hi haibo,

Here you need to download the Chinese fonts first and put it into the directory /usr/lib/fonts on your board. Then set the font you need in the main.cpp of QT.

You also can set the font type you like. Take " SimSun" as an example:

	QApplication a(argc, argv);
	QFont font;
	font.setPixelSize(20);
	font.setFamily("SimSun");
	QApplication::setFont(font);
	...

Hope this can help you.

Have a great day,
Dan
