Please update the default font for Chinese users

The default font for Chinese(both Simplified and Traditional) apparently doesn’t support the full character set. The missing characters uses Windows fallback font and as a result, the UI is a mixture of Sans and Serif characters.
The program by default seems to use a Japanese font, and the characters that doesn’t fallback to Windows default doesn’t have correct regional shape.
Please see the screenshot below and notice how some characters have serifs while others don’t.
