Good luck.

1. Panpan is a well-known trademark in China, one of the top ten brands of security doors, a Chinese famous brand, and ranks first in sales in the country. Sheman is high-end, but the after-sales service is not good.

2. The Panpan brand has a good reputation in the same industry. The company's products include protective windows, rolling shutter doors, etc. Sheman's reputation is not as good as Panpan's.
