I have just been there. It will take an afternoon to walk around. You can go in from the South Gate of Tsinghua 12, take some photos at the door, and then go in and have a general browse. Actually, it's nothing. After going to Tsinghua Campus, I went straight to Ximen, went to Peking University, saw the Weiming Lake, and took photos at Ximen. Then walk to Yuanmingyuan, about 20 minutes. Yuanmingyuan is quite big. It takes about two and a half hours to stroll down. Go straight to Fuhai, go north to Dashuifa site, and then take the subway to the panoramic sand table to see the south gate. I am in a hurry to go on a business trip, so I have no time to go shopping. I am tired of shopping in a hurry.
