In "Guangyun," it is pronounced chā (entering tone), from chū (初) and yá (牙). In "Jiyun," it is pronounced chā (entering tone), from chū (初) and jiā (加). The pronunciation is chā. It is the same as the character 艖. "Yupian" explains it as meaning 䒀. It is also the name of a type of fish. Yang Shen said: it is the current Chátóu suō xiàng biān. "Zhengzitong" commentary states: the Chátóu biān is shaped like a boat, just as 舴艋舟 is written as 蚱蜢舟; both are analogies based on shape, not that 舴艋 is actually a grasshopper. To call 䑡 the name of a fish is incorrect.
