The width of Chinese characters in CJK fonts should be twice the width of
English characters.
At present, the Chinese characters in the CJK font can not be clearly
recognized.
It is not standard to observe the width of English and Chinese characters.
If it is changed to standard width display, can the problem of blurring of
Chinese characters be solved?


At the same time, it is recommended to add monospace font or ttf font
display.
