How to change the Chinese font at will in Visual Studio

When the font you set in vs does not support Chinese characters (for example, consolas), vs uses a file to decide which Chinese font to use.
This file is:
% USERPROFILE % \ Application Data \ Microsoft \ Visual Studio \ 9.0 \ vsfontlk. dat

This file is in the text format, UTF16 encoding, with Bom. Open it in a proper editor and check this line.
0804 | nsimsun | new
0804 is a hexadecimal value, and the corresponding 10 hexadecimal value is 2052, that is, the Lang ID of the Chinese PRC. The font is behind it.
Change this line
0804 |

Re-open vs. The font has changed! (Only the new Chinese looks small)
