I want to go to Beijing in a few days and go by train. It will take about three and a half days. Can you make a strategy for me? Only visit places of interest, not the Great Wall.

Square, monument, memorial hall, Great Hall of the People, half-day tour. Go to the front door and get it done in half a day.

Summer Palace, Yuanmingyuan, Bird's Nest, Water Cube, one-day tour.

The Summer Palace and Yuanmingyuan can take Metro Line 2 through the front door, change to Line 4 at Xuanwumen, and arrive at Beigongmen and Yuanmingyuan Station respectively.

Bird's Nest and Water Cube, you can take Line 4 at Yuanmingyuan Station, transfer to Line 10 at Huang Zhuang, Haidian, and transfer to Line 8 at Beitucheng.

Then take Line 8, change to Line 2 at Gulou Street Station and return to the front door.

One-day tour of the Forbidden City, Beihai and Gongwangfu.

The front door is within walking distance.

Finally, after visiting Gongwangfu, take Line 6 at Beihai North Station, transfer to Line 2 at Chegongzhuang and return to the front door.

One-day tour of Temple of Heaven, Lama Temple and Wangfujing.

Take Line 2 at Qianmen, change to Line 5 at Chongwenmen, arrive at the East Gate of the Temple of Heaven, and visit the Temple of Heaven.

Then take Line 5 at the East Gate of the Temple of Heaven to the Lama Temple.

After that, the Lama Temple took Line 5 to Dongdan and visited Wangfujing.

=================================================

If you watch the flag raising, it is recommended to live near the front door and walk there.
