1 - Is there an entry for koi fish? I searched up “锦鲤“ and it wasn't there. 2 - 鱼 resembles a fish swimming upwards. The top part represents the head, 田 resembles the body and fins of the fish and 一 represents the tail of the fish. 3 - Are there any common idioms or expressions that use 鱼? (yú) 4 - What is the difference between 鱼 and 鱼肉 (yú, yúròu)?

1 - 是否有关于锦鲤的条目？我搜索了“锦鲤”但并未找到。2 - 该图案仿佛一条逆水而游的鱼。图案的上部代表头部，田字图案则象征鱼的躯干和鳍，而一则代表鱼的尾巴。3 - 是否有使用‘鱼’（yú）的常见成语或表达？4 - ‘鱼’（yú）与‘鱼肉’（yú, yúròu）之间有何区别？
