One thing troubles us, and seeking foreign exchange, foreign exchange and knowledge of the master. . . Younger brother of a client, general trade export declarations, the import and export rights under the company just to do so is not very high amount of foreign exchange. Then one vote out of stock the day before yesterday, is over, and he find himself in the foreign exchange bureau before shipping off to a pre-settlement of the contract number. Numbers can be normal at this settlement of the contract. But then I shipped, contract number to the wrong, I was not the pre-settlement of the contract number. Customs formalities have been completed on my side, and he wanted me to help him change the contract number in the customs, I tried. Does not work. . . How to deal with now? He and I also like a number of ways, but not yet implemented down. Hope there is a master to give advice. . . . . .
