Well, life is experience, should we sit here for 30 years without new experience? in this case, why do we need long life? life isn't just for bread and comfort but meaningful. ask youself what is your dream and try to approach and make your life colorful. I an in EU now and also have very comfortable life, I have dicided to go back china in one year. If we can survive in a foreign country, i will survive in our own country. this is my idea.
