I was born in 70's and experienced many changes in my life. When I started to remember something, I have no socks to eat except rice and noodle. Many people often wore yellow clothes and seldom to travel to other places. Having a Bicycle is many families’ dream. Sew machine is often the trousseau of many girls. Watch is costful goods. At those ages, we are lack of everything. If you have money, you can not buy anything. 30 years past, automobile is everywhere in our daily life. Travel abroad is easy for many people. Today, the market is full of everything.

But, I have only missed our previous fresh air and clear rivers. Hope that our beautiful environment will come back in the next 30 years.
