If you think the food is delicious, we always use the word “鲜”. (such as “The food 真鲜.”) This chinese character is combined with “鱼” （fish）and “羊” （mutton）. Why?
There is a traditonal chinese food named “羊方藏鱼“. The chinese people find if they cook fish and mutton together, both of them will be more delicious.
Do you doubt about that? Try it!
