Climbing to the second floor... by meteorologist1
You can climb onto the Tiananmen Gate to get a good view of Tiananmen Square. The Tiananmen Gate's second floor used to be closed to the public, but now you can look at the meeting areas of political leaders. Very interesting. It's just that you have to go through very strict security upon entering.
