白马非马

A person of the state of Song named Er Shuo was noted for his eloquence（口才，雄辩） at his times. On one from the famous She Xia school of the state of Qi could defeat him in his argument that "a white horse is not a horse".

Nevertheless when he passed the pass riding his white horse, he would pay the horse-passing tax and never argued with those guards that a white horse is not a horse.

宋国人儿说能言善辩著名于时，当他坚持‘白马非马’这一学术观点时，齐国著名的稷下学派没有一个人能驳倒他的观点。

然而，他骑白马通过关卡时，还是如数交纳马匹过关费，并不和关卡的官吏争执白马是不是马。
