Following Liu Bang was Emperor Xiaowen，but Queen Lu was the actual power in the court。Lu Jia then did not want to remain in the court，and he simply resigned and went back home。His five sons had all settled in the countryside and became peasants。He himself often took the chariot and a sword with him。He took delight in climbing mountains and rowing boats，usually acpanied by singers and dancers。
Once he called up all of his sons，and in an order-ing more than a cautioning tone told them：“Today I will enter into an agreement with you all。On whichever day from today on，to whomever of you I may make a visit，I'll have a ten-day stay。You are to entertain each of my train。If I should unfortunately die in one of your homes，that son could luckily keep my chariot and horses and my sword。My ing and going may happen many times。You should not feel tired and bored。If by all this you are annoyed at me，I will punish you and you are not to blame me for it。”
So later“Many Times It Happens，There Is Nothing New“became an idiom which means something may occur so many times that people do not consider it at all new。
