Lend money to the United States, then American banks overdraw people's consumption with credit cards, then poor Americans overdraw credit cards to buy goods from China, and finally China earns foreign exchange through exports. In the future, foreign exchange will be used to help Africa, the Middle East, South Korea and Southeast Asia, and then state-owned units will go overseas to dig mines and repair railways to run love schools and volunteer doctors to go to Africa. In the future, African brothers should pay tribute to CN, and philanthropist in the world is also a fool!
