Do you need nucleic acid to go to Nanjing by subway?

Don't. According to the latest cross-regional policy, Jurong doesn't need nucleic acid to go to Nanjing by subway, and now it doesn't need nucleic acid across regions. The latest notice shows that public transport vehicles such as subways, buses, ferries, taxis, and online car rides will no longer check negative nucleic acid test certificates and health codes.
