You can't. Huatuo's round of playing cards. Only green bags can be used. At this time, you can use either hand as a peach. Lightning belongs to the cards in the referee's area, and the cards in the referee's area do not belong to anyone. Only hands and equipment are personal cards. You can use first aid outside Huatuo Round and use any red card (hearts or diamonds) as a peach. Any red card refers to the equipment card and the hand card. Therefore, hanging lightning Hua Tuo cannot be used, including being happy. Because the cards in the referee's area don't belong to anyone.

Hope to adopt
