I live in Shenzhen, one of the most four influential cities in China. Three of the most important kinds of stock and flow in my city are technician, traffic, and labor worker. Firstly, Shenzhen is a city with well-developed high-tech industry, for which many skilled and professional people(with their techniques) come to Shenzhen to get their job that related to high-tech industry. The corporation of them and their companies can together turn the raw material or new ideas into valuable final products (e.g. Dji drone) that boost the development of the industry and benefits consumers. Secondly, every day people are flowing around the city, and many of them use the metro system, from one place to another. Thirdly, labor workers from different places constitute the major group in the city, and they are comparatively more populous. Every year, this group of people come to Shenzhen to earn higher salaries, and they use the money to raise their families (mostly in their hometowns); and when the vacations (especially Chinese New Year) are coming, most of them will go home while bringing many gifts and the deposit, to enjoy the ambience and living with their families.
