Jieyang Niuban, commonly known as lumpy milk, is a food with Chaoshan characteristics. It has some characteristics of salted products and Chaoshan snacks.

Niu Qiang, some people call it Niu Huan. According to the definition of Ci Hai Yu Ci, you are a "black and white cow". You take the homophonic sound of the tide instead of its meaning. It is not standard for Chaoshan market malls to write cows as cow bells. Milk is liquid, while cowbells are lumps.

The method of making cattle carry is to pour milk into a pot, cook it, and mix it with proper amount of vinegar to make it coagulate. After semi-cooling, scoop it up with a spoon, knead it into granules by hand, and put it into the first dissolved salt water. Its color is snow-white, it has the smell of milk, and there are obvious fingerprints on the grain, which is very human and has good color, fragrance, taste and affection. -Mr. Chen Hanchu, a folklorist, wrote the account of "Eating in Chaoshan, Chaoshan Time-honored Cuisine".

beef jerky is a more beautiful snack than milk. It not only retains the rich nutrition of milk, but also contains a lot of nutrients such as calcium, fat, protein, carbohydrates and vitamins B2, D3 and B12. It is also a vegetarian food without the original fishy smell of milk, which is more widely loved by consumers. In the production process, ingredients such as vinegar and salt are added to make some nutrients that are difficult to be absorbed by the human body dissolve, and the nutrients are more easily absorbed. Folks call it "digestion". From the perspective of the homology theory of dietotherapy, cowbell is a kind of food with medical and health care functions.

Baita Town, Jieyang is a famous milk producing area, where Bao co-produces milk and Tongkeng produces cattle handles. Of course, other towns also make cow bells. Cow bell is a favorite snack of the broad masses of people. In the streets and lanes, under the five-legged masonry, cattle sellers and hawkers often squat down. After Guan Ye Palace in Rongcheng (surnamed Chen) and the alley in Nanshi (surnamed Huang), each person has a small stall, which specializes in selling cowbells. This is the characteristic of selling cowbells in Jieyang.

In Chaoshan's writings about Chaoshan cuisine, as well as the old and new records, there is no description of Niu Qiang. Although, Niu Qiang is a well-known snack in Jieyang; However, in the Pearl River Delta area, beef jerky is a well-known delicacy.
