Roasted pig's trotters, a new special barbecue with good color, fragrance and taste, has been sought after by the vast number of diners once it was launched. Pig's trotters are rich in collagen and protein, and their fat content is lower than that of fat meat. They have always been one of the best foods popular among diners. In folk, they call pig's trotters "beauty food", which can be compared with bear's paw, inherit the traditional food culture of Chinese people, and break through the traditional cooking methods on this basis. Roasting pig's trotters perfectly combines pig's trotters with barbecue, thus creating a human food.
