If you enjoy visiting cultural treasures and appreciating beautiful architecture, the Forbidden City in China is a must visit. You can go there via subway by going down at the Tian’anmen East station (along Line 1).
It took us two hours to go around (including Tiananmen Square). We did not go beyond the Hall of Supreme Harmony (Tai He Dian) because it’s the biggest ans the succeeding palaces are smaller. However, we were still able to go at the back of Tai He Dian which is the Hall of Central Harmony.
