余光中说：
假如你想找一名古人去旅行，一定不要找李白，他太过于狂傲，不知天高地厚； 也不要找杜甫，他的命太苦，对生活没有信心； 要找就找苏东坡，他是一个懂得让自己的生活变得有趣的人。
If you want to find an ancient person to travel together, you must not look for Li Bai, he is a little too arrogant; also do not look for Du Fu, his life is too hard, he has no confidence in life; Su Dong-po is a good candidate, who makes life interesting.
