Excuse me, which website has better effect on fastener export? What kind of fairness is effective?

If there is a trade fair, it will be May 25th-26th in the near future. Golden Spider has a fastener exhibition in Chengdu. At that time, domestic and foreign buyers and suppliers will participate. I suggest you visit it then. . Website, I think Golden Spider will be better. After all, people are professional households, while Ali is a department store, not to mention China Screw Net. Its boss also makes his own fasteners. Even if there is a good order, it may be done by himself, which is unfair. . .
