I heard about Baoding Four Treasures for the first time. In my later years, I said Baoding Sambo, that is, the iron ball noodle sauce is not old in spring.

The first treasure: Baoding iron ball (commonly known as fitness ball) is not only an entertainment tool, but also a fitness function. When I was a child, I also knew that the iron ball was produced in Baoding Knife and Shear Factory, and was called blacksmith Wang Tieqiu. I don't know what manufacturer produced it now, but you can see many products on the market.

The second treasure: "Baoding Noodle Sauce", which was first produced in the tenth year of Qing Emperor Kangxi, has a history of nearly 400 years. It has a good quality and a long reputation. It is an ideal cooking seasoning. Baoding Huaimao Pickle Factory has produced flour paste so far. Sales are very good, and most people in Baoding have been buying them.

The third treasure: "Baoding is young in spring", also known as "potherb mustard", a common vegetable, which belongs to mustard and looks like radish and cherry. Baoding has a long history of cultivation, cheap and good quality, and is deeply loved by people. Some are sold fresh and some are preserved. Now Baoding Huaimao pickles factory also produces them, but few people eat them.

If Baoding is Four Treasures of the Study, can't donkey meat be burned? Baoding donkey meat is rampant in fire, and it is difficult to distinguish between true and false, so I won't comment, but I can't recommend it here, so as not to be criticized for being suspected of advertising.
