What is the whole story of the Chinese aunt stealing gold?

To give you an example, I borrowed a bag of apples from someone, worth 10 yuan, and then sold them for 10 yuan. Two days later, the price of apples dropped, and a bag of apples was only worth 5 yuan. At this time, I paid back the money to the person who lent me the apples. The price was only 5 yuan according to the market price, so I earned 5 yuan in the meantime. This is short Apple price. Shorting the price of gold, the same principle applies. If a large amount of gold is invested in the market and the price of gold falls, the price difference can be obtained. The only difference in China this time is that there are too many people buying gold, so the supply and demand relationship has not changed significantly, and the price of gold has not fallen significantly. However, the price of gold has continued to fall recently, indicating that their short selling operation has been successful.
