How did Hangzhou Boniu Architectural Design Consulting Co., Ltd. review their drawings?

I know them. The previous unit worked with them. People there are very responsible, and civil air defense construction drawings can be reviewed. Their qualifications are quite complete. I have been to their place. There is a Huaxing Century Building in West Lake District of Hangzhou, which seems to be on the eighth floor. I can't remember clearly. You can learn about it, I hope it will help you.
