You can choose a piece of braised pork or a rib for each meal. There are more CDs in the restaurant... This is the "self-service rice-making artifact" launched by Gansu Jiuquan Vocational and Technical College. Dishes-put a spoon-swipe your card, you can hit a dish in 3 to 5 seconds, and hit as much as you eat. It is inappropriate to "make leftover customers" and refuse "waste on the tip of your tongue."

According to reports, the school saved more than 330 kilograms of food every day after the "self-service meal artifact" was launched. On a 10-month basis, it saved 99 tons of food every year.
