Hard card: Touch the Hu card yourself, and the card has no God of Wealth or the God of Wealth returns (God of Wealth represents his own card and does not replace other cards).
A god of wealth grabbed Hu (it had been knocked out before, and the fourth card was caught at the back. If you take it out, others will be like Hu's cards, so others' Hu's cards are hard cards)
You have three cards of God of Wealth in your hand. You can play Hu cards if they don't match the type of Hu cards (hard cards).
Soft card: There is a god of wealth in the Hu card, but not other cards.
