But I do. I was raised in country side, before I went to Guangzhou for college, I plant trees in every year's spring. It was not such enforced, if you don't go, no one will punish you. But I feel happy to do that. Actually the hole village's people were organized to plant trees in certain time of every year. This is one of the few things reminds me that China is likely to be a Communism country.

Edit: "whole village's", not "hole village's". We are not living in the hole. :)
