Central TV's 3-15 evening party broadcast process, exposed a number of typical examples of consumer abuse. But especially concerned about the pickle pickling problem, a short time, "315 old altar pickles", "old altar pickle package is actually clay pit pickling" and other phrases on the microblogging hot search list. After the exposure of the video of the production process of its sauerkraut buns, but also provoked the anger of the crowd, and the old altar pickled beef noodles belong to the Master Kong company has also become the focus of the crusade.

The sauerkraut buns in Uni-Tan's beef noodles are not produced in its own workshop, but are outsourced to a vegetable reprocessing company called "Flag Vegetable Industry" in Huarong County, Hunan Province. The official line from the company is that products for export are processed in its own workshop, while products sold locally are outsourced to a team of workers.

Vegetables in the washing plant were placed haphazardly on the ground, and the pickling area was an open pit with no aseptic measures. Workers even stepped on the vegetables with their bare feet and casually threw their smoked cigarettes on the pickles. Even without any knowledge related to food safety indicators, the general public can tell that such a production environment and hygienic conditions are absolutely not in line with food safety norms.

After the CCTV disclosure and the condemnation of netizens, Master Kong issued an official apology statement and quickly took down the related instant noodle products.
