Huajia is a kind of seafood, which lives in seawater environment. Generally speaking, it is difficult to live without seawater, but obviously we can't have seawater, so we can only rely on salt water to simulate seawater. After adding salt, wait for a while, about 15-20 minutes. If the nails start to appear, it proves salty enough to keep.

The second method is refrigeration.

If there is, ask the stall owner to help you put some seawater in the bag of flower armor, pour it into the basin when you get home, and then put it in the freezer (note that it is refrigerated, not frozen). If you want to keep the armor you bought until the next day, you can put it in salt water. After adding salt, wait for about 20 minutes, and the buds begin to appear, which proves that they are salty enough to be raised.

Hua Jia is a creature that lives in lagoons or the sea, and it is generally difficult to feed. It can last seven to ten days at most. If you want to be bigger, you can raise some saline-alkali plants and add a little soil.
