On this day, 64 years ago, on May 9, 1961 (March 25, 1961, the lunar calendar), Zhu De wrote a letter to strongly explain the shortcomings of public canteens. On May 9, 1961, Zhu De wrote to Mao Zedong, saying that Sichuan members ate "two cigarettes", that is, they cooked one in the canteen, and the members picked up rice home and then processed another, which wasted a lot of manpower and material resources. The Shaanxi Provincial Party Committee has a very strong reaction to the canteen. Most people are willing to go home and cook their own meals, while a few are willing to stay in the canteen to eat. The masses said that there are five bad things in the canteen: (1) members don't eat enough; (2) Waste of labor;(3) Waste of time;(4) It is inconvenient to eat on rainy days;(5) Eat confused noodles all year round. Cadres reported that there were 11 "smashed" in the canteen (meaning to make trouble):(1) smashed his eyes; (2) Smashed the meeting;(3) Smashed the criticism;(4) Smashed the face;(5) Smashed the superior;(6) Smashed the masses; (7) Smashed labor costs;(8) Smashed trees;(9) Smashed livestock grass;(10) Smashed pots;(11) The cook staff smashed ghost days.
