Don't buy profitable software in the future.

What you bought is pirated, right? You can call Chuangying Software Company to complain. I am also a user of Chuangying software. I have used it for five or six years, and it has been very good. There is no such thing as changing dogs. Chuangying's service is timely. You can directly call Chuangying Company to complain. The function of Chuangying software is very practical: different glasses in the same series, such as 5+9A+5, 5+ 12A+5, are all heat-insulating glasses. How to make the software automatically match the appropriate layering? Other peer software is impossible.
