There are: Chinese regular script, Zhong Yi regular script (Windows font, called regular script in Windows), Founder regular script, regular script -GB23 12, etc.
Italic -GB23 12: The standard GB23 12- 1980 is realized, hence the name, which is also 6763 characters. GB23 12 is a national standard.
It is said that Zhong Yi regular script, China regular script and Founder regular script all come from the same prototype design. There is little difference between Chinese and Yi regular script, but there are differences, which can be seen by magnifying observation. Which part of China people is more beautiful is a matter of opinion.
