The first thing they do when they come to Shaanxi is to get into Xi'an Muslim Street, which used to be a trading market for cattle and sheep in the early years, so all kinds of snacks are mainly beef and sheep. There are nearly ten preserved beef and mutton shops alone, in addition to Liu Jixiao, who is third on the list, Lao Tong's family is also very famous.

The old boy's house is one of the oldest bacon shops in Xi'an. Similar to many legendary time-honored brands, Lao Tongjia borrowed the "Cixi Allusion" for publicity, and even traced the history of the store back to 1773. Even so, Lao Tong's family is still slightly inferior to Liu Jixiao (No. 3) in popularity.

Lao Tong's cured beef and mutton production is not much different from Liu Jixiao's family, in fact, although the restaurant that makes this bacon has a slight difference in cooking skills, there is no substantial difference in the finished product, the only remaining subtle difference is the softness and saltiness of the meat, which can be said to be a taste for diners at this point. Lao Tong's cured mutton is worth a try, it is presented as the pink color of the meat product when it is fresh, and after the grain is cut, the inside is white and red, the fat and thin are staggered, and the mutton fat is interspersed with the lean meat. It is tender in the mouth, rich in aroma, and has a finer and creamier texture than cured beef. The practice of cured beef and mutton is very exquisite, fresh beef and mutton are selected, put into the well water with green salt and miscanthus (sodium sulfate) to marinate for several days, and then simmer in brine mixed with star anise, cinnamon, grass fruit, pepper, cumin and other spices before it can be sold on stage.

Due to the increasingly loud signboard of the old boy's house in Yuanzhipo, many counterfeit shops have opened in the Huifang area. Although there is not much difference in the finished product, most diners will still have a grudge against it, so it is recommended that diners who have this idea look for a signboard with the words "Lao Tong's Home Interviewed by CCTV".
