Zhengzhou, like most Chinese cities, is generally safe for solo female travelers due to pandemic restrictions, strong law enforcement, a low crime rate, and reliable public transportation. As with any destination, standard precautions such as using trusted sources for travel, avoiding isolated areas, and not sharing personal details with strangers are advised. Emergencies can be attended by dialling 110, the national police hotline. Though, it's worth noting that English services might be limited.
