Heaven and earth lock on aluminum varieties ... if it is, it is a very sad situation of warehouse locking operation. Heaven-earth lock is a kind of trading method using circular warehouse lock. Finally, after the transaction is completed, a lot of orders are left at a very high point, and empty orders are left at a very low point, which leads to the situation that it cannot be unlocked. Locking operation was popular in Southeast Asia for some time. But it seems that our country has never heard of good work. Because locking the warehouse is really easy, unlocking it is much more difficult than opening it. Just avoiding the problem temporarily does not mean that the problem has been eliminated, and the problem may be even bigger in the future. I hope the introduction can help you.
