最近老看见有人讨论带钱或汇款的事，凑凑热闹。

汇款的关键在汇出方。以前是现汇就能汇，如是现钞就麻烦，至少要个手续费。两年前规矩改了，关键变成了汇出的人。有些网友在争论能不能汇或能汇多少时没抓住重点。现在的关键是开户的那个人得是有外国长期居住资格的。打个比方，有财他哥从成都中行给他汇5000美金，if the account is under 有财's name, and his brother is authorized 委托人，可以的；if the money is under the name of his brother, who doesn't have at least a long term visa, then it's not OK. 因此，各位如有需要，不妨保留一个户口在国内。
至于用某某卡贵或便宜，现金放鞋底好还是腰里好，各路英雄有自己的经验，我就不关公面前舞大刀了。
