It is suggested that the landlord go to Jiming Temple first, and there are few people in the morning. Tickets 10 yuan. Jiming Temple is not big, so it may take 1 to 2 hours to visit it.
Then take the bus 1 1 from Jiming Temple to Nanda.
At noon, you can go for a walk on the campus of Nantah, have a meal in the canteen there by the way, and take a walk on the campus after eating. (It also takes about 1-2 hours)
Take the subway from Nanda and get off at minggugong station, which is the Nanjing Museum.
Go to Nanjing Museum in the afternoon. Nanjing Museum is free, and there are many things in it, which can be played all afternoon. (time is about 3-4 hours)
Finally, I wish you a happy stay in Nanjing!
