There must be control measures. You just put the money in. This is called foreign hot money inflow. People can directly suspect that you are laundering money and have the right to cancel your account, so that you can't take out a penny.

Of course, if the amount is very small, thousands, or 120 thousand, let someone bring it in, or directly call the smuggler's account several times. If it is too much, I suggest you take the trade route.
