Personally, I think e-commerce, healthcare, tourism and education are the industries with high development potential in Zhengzhou. E-commerce is benefiting from the popularization of the Internet, healthcare is seeing increased demand due to aging and health awareness, and tourism has potential due to its rich tourism resources. The education and training industry is also growing rapidly due to increased social competition. To make money, you need to combine market demand, competition and personal interest to choose the right industry, and constantly improve your own ability.
