It's not expensive, it's not joining, and there are no such messy expenses. Besides, learning technology is a lifelong job, but there is a good way out after learning it. I know that Nanjing Gaoji Shaanxi noodle restaurant, which is very famous and the business is very good. The boss's grandparents used to make Shaanxi noodles, but many people learn from her ancestral skills. What do you say? Go and see for yourself. Don't miss the good opportunity.
