Domestic software includes Fuyi, TOP Top, etc. Fuyi is easier to use, and Shenzhen is more used.

There are ET and lectra abroad, among which ET is used the most (at least in Guangdong)

If you want to learn, you'd better learn ET or Fuyi, because more people use it.

But it doesn't matter. After learning one software, you can quickly adapt to other software, 1 week is unnecessary.
