Method 1: sell foreign exchange forward contracts or foreign exchange futures. If it is expected that the foreign currency of the company's income will depreciate, it can be short in forward contracts or futures contracts. If the currency depreciates, the losses in the spot market can be compensated by the profits in the futures market.

Method 2: Buy foreign exchange put options. Similarly, the decline in foreign exchange prices can make the company profit from options, thus making up for the loss of cash exchange. The disadvantage is that it requires a certain option fee.

Method 3: It is negative to advance or postpone the time of earning foreign exchange.

Method 4: Carry out barter trade, and directly remove the intermediate medium of money, without foreign exchange risk.
