Write 告(gào)(tell) in Chinese charater

告(gào)

Origin:

甲骨文中“告”的字形是上面一个“牛”字，下面一个“口”字，合起来表示祭祀时，人们献上一头牛，并进行祷告的情景，后来，“告”的意思逐渐普通化，泛指“告诉”“表达”和“诉说”。
On ancient oracle bone inscriptions, “告” was composed of “牛” (cow) on top and “口” (mouth) on the bottom, together meaning that people sacrifice a cow and pray in a religious ceremony. Later, the meaning of “告” gradually became more general, and now refers to expressing and telling.
