I can't directly understand and answer the current actual situation, but I can provide some reference materials:

-Buckling bowls and cauldrons is one of the characteristics of Henan, so in Zhengzhou, the capital city of Henan, I believe many people will like and consume this dish. Zhengzhou is an economically developed city with a relatively high consumption level. Therefore, if you can make braised cauldron dishes with unique taste, good quality and reasonable price, the possibility of making money by selling braised cauldron dishes in Zhengzhou should be considerable. Of course, we also need to consider factors such as competition and market supply and demand. If there are already a large number of buckle pot sellers in the market and the consumer demand is insufficient, it may be more difficult to make money. To sum up, it depends on the market, the products and the operation whether you can make money by selling buckle bowls in Zhengzhou.
