Although I don't like Gu Ailing, seeing many people say that "the U.S. raised her" is also ridiculous. China has a centralized training system for athletes, while the U.S. government hardly directly trains athletes. The government also does not provide financial support to the Olympic team. The sports industry in the U.S. is highly market-oriented and commercialized. To achieve success in sports, you need top private coaches + professional training facilities and long-term support and pressure from parents. This requires a family to invest long-term resources. In simple terms, it's her mom or investors who are early on making a risky investment. You can think of Gu Ailing as a "company." The investors are her mom and other financial backers. When this company becomes profitable, it's their choice where to go to maximize profits. In fact, in front of any national institution, it's always the parents who raise the children. The state and government are just ruthless tax machines. They have no right to talk about nurturing.
