Hi, I will be in Nanjing for a short over transit of 7 hours, is there any place that I can visit?

For a 7-hour transit in Nanjing, recommend visiting the Confucius Temple-Qinhuai River Scenic Belt. Take Metro Line S1 to Line 3 from Lukou Airport—about 1 hour direct. Explore ancient sites like Jiangnan Imperial Examination Hall and Wende Bridge; perfect for photos of red walls, lanterns, and riverside views. Try quick local snacks like duck blood vermicelli soup and beef potstickers. Allow 4 hours for sightseeing and leave 2 hours before your flight for the return trip to avoid delays.
