An empty position is an empty position, which means selling. An empty order is an empty order, which means buying. A bull is a bull, which means buying. Long flat order, that is, selling. As can be seen from the above, short positions, long positions are selling, short positions, and long positions are buying. The opponent who sells is naturally bought, and the opponent who buys is naturally sold. So, open the opponent's plate-empty flat, open more.
