Wish to spend a day visiting the Presidential Palace, Kid Square, the main branch of Vanguard Books, the Six Dynasties Museum, the 1912 Block, and the Xincheng Pedestrian Street. How should I go?

Meiqin is Deji Plaza. You can first go to the museum (remember to book in advance) ~ Presidential Palace ~ Pioneer Bookstore ~ ​​Deji (just at Xinjiekou) ~ 1912 (go at night)
Block 1912 is right at the exit of the Presidential Palace. The Museum of the Six Dynasties is across the road from the Presidential Palace. It is very convenient to go out. You can take a subway, bus or taxi.
At the intersection of 1912 Street, the Presidential Palace, library, Six Dynasties Museum, and Jiangsu Art Museum are all together, so you can spend a day together.
They are all nearby and not far away. I think we can finish the tour. One day is too tight for immersive play.
The route is not clear, but I really can’t make it in one day. I also came here to travel. I went to Ming Xiaoling Mausoleum and Sun Yat-sen Mausoleum on the first day. I ran around there for a whole day. On the second day, I went to the Bandstand and Meiling Palace. I was tired and didn’t want to leave. Moving on, I went to Chaotian Palace and Da Baoen Temple on the third day… and then rested. We will talk about it later.

Don’t go to the Presidential Palace, there’s nothing there, just 2 office buildings
The museum and the museum are two units! If you plan to go to a museum, you should make a reservation at least one week in advance, but you may not be able to get an appointment, it’s so popular!
Depending on the tour time of the Presidential Palace and the museum, in-depth tours and explanations will each take 2-3 hours, one morning + one afternoon, so time is quite tight.
