Introduction to the Zheng Family Industrial Reproduction Exhibition Hall: "Zheng Family Industrial Reproduction" reproduces the two industries run by Lin Feng's father in Wangkui through two miniature scenes of "Jin Da Qian Hao" and "Deyuan Wood Factory". It records the transitional stage of the Zheng family's abandonment of farming and doing business, confirms that the family was well off at that time, and laid a solid foundation for Lin Feng to study in Guanzhong, get in touch with progressive ideas, and embark on the road of revolution.
