I live in Shenzhen. Shenzhen is beautiful now. Five years ago, there was no subway. But now, there is a subway. It is very continent for the citizen. Seven years ago, there were a lot of green trees. Those trees were flourishing. But now, these trees are very small. The weather becomes hotter and hotter.
