Empty orders change hands: if the original selling orders in hand are to be closed, they must be repurchased. Someone else must have sold it at this time. If he opened a position, the position in the market did not change at this time, but the sell order was changed from my hand to his hand. This is called empty exchange.
Simply put, changing hands means: the original short position is bought and closed, and the new short position is sold and opened, and the position remains unchanged.
