Zhengzhou Science & Technology Museum

Has a theme park inside with a quaint Ferris Wheel that is worth riding.

Museum inside a rather garish double pagoda that looms over February 7 Square. Inside there are exhibits explaining the city's development.

You can see remnants of the wall in the east side of town. Be warned: these mounds are not terribly impressive.

The Zhengzhou Confucius Temple is a historical building complex dedicated to Confucius. The first temple was built here in the first century AD, and it has been rebuilt several times after being damaged or destroyed by wars and fires. The Dacheng Hall, dating from the Qing Dynasty, is the main historic building in the complex, while many of the other buildings are modern reconstructions. The Dacheng Hall, which dates from the Qing Dynasty, is the main building of historical value. The other buildings that make up the complex are largely modern reconstructions.

This monolithic pyramid-shaped museum is worth a visit (the main building is under renovation as of August 2019, but the museum is still open). Learn about ancient civilizations in the area (most of which were not based in Zhengzhou, but nearby cities such as Kaifeng and Luoyang), and even see a dinosaur bone or two in the area. The museum is one of the three key museums in China along with one in Beijing. If you are into modern art, this is not the place for you. It generally has acceptable squat toilets on the first floor. There is an English audio tour you can rent, and there are cheapish lockers to store your stuff. Come to see old pottery from the Song dynasty, old bells, bronzes, things like that, but anything more recent does not have English captions. Don't miss the Ivory cabbage. Across the street is a coffee house that makes ok tea and coffee for about ¥30 and has comfortable chairs.
