People here should learn from Hong Kong's subway system. Millions of people use the subway in HK, but the people are always so polite, clean and organized.
When I was in Taiwan this summer, I noticed that in the subway,
1. Hardly anyone sat on the special seats.
2. Most of time, people let others come out first before go in.
3. No one eat ice cream or even eat anything hardly.
I should add #12 to little prince:
1. Do not try to get in when the door is about to close. Wait for the next train.
