Why should we leave some regrets when traveling?

You don't have to see through all the scenery, leaving one or two places unseen is the best reason to come again next time. Liu Haisu, a great painter, went to Huangshan Mountain for ten times, and every time he made new discoveries, he was able to rekindle his creative passion until he was too old to go on stage. He still felt that he had many regrets and became a beautiful talk in the painting world. From this point of view, we have seen so many places of interest in a hurry, and we don't know how many regrets we left behind, but we didn't realize it ourselves. Of course, leaving some regrets is not deliberately to retain, but also deliberately to leave some tails for things that could have been satisfactory. Leave some regrets, that is to say, indifferent and peaceful. Don't be too eager, nor too rich and famous. Sometimes you have to argue according to reason, and don't let an inch difference. Sometimes, we should go with the times, face up to and admit those regrets that cannot be changed. It is Dongpo's words: "People have joys and sorrows, and the moon has ups and downs. This matter is ancient and difficult. "
