For example, one share 10, everyone started to sell, and you also borrowed shares to sell 100, and got 1000, and then this fell to 1 point, and you bought back 100 for one yuan, making 999, right? The highest short price is the price you sell, and it can't be higher. Any higher, you'll lose. If you do more, the price will be higher, so it will always be a bull market to make big money, and a bear market to keep money.
