"I have never thought about what to do as the richest man. I just work hard every day. To say that I am the richest man, it's just because many (enterprises) are not listed. I think the most important factor for success is the outlook on life and world view, and then is hard work. I am not smart enough, but I work very hard, and I only know how to make things better day by day. There are two roads in life: one is to walk on a red carpet with flowers all around and an Aladdin lamp given to you, you can get whatever you want. That's no fun. After crossing the river and climbing over the high mountain, when you cool off on the top of the mountain, happiness will come."
