Poems reflecting the major events that took place between China 1960 and 1969.

1July 6, 960, the Soviet government suddenly unilaterally tore up 343 expert contracts and supplementary books, and 257 scientific and technological cooperation projects, accounting for 600 contracts. And note that the government of China unilaterally decided to withdraw all experts in China from July 28th, 1960 to September 28th, 1 and stop sending 900 experts. Although the China government has repeatedly retained it, the Soviet side has always insisted. When the Soviet experts retreated, they took all the drawings, plans and materials with them, stopped supplying important equipment urgently needed for China's construction, and greatly reduced the supply of complete sets of equipment and key components of various equipment. The treachery of the Soviet revisionist group headed by Lu has brought the construction of more than 250 enterprises and institutions in China to a standstill or semi-standstill, which has caused great losses to China's economic construction.

At the same time,1July, 960, Khrushchev forced the China government to pay its debts. During Stalin's period, the Soviet government gave China some loans. China's weapons purchased from the Soviet Union during the War to Resist US Aggression and Aid Korea were also recorded in the form of loans, totaling more than 5.8 billion yuan. A lot of loans are used to buy weapons. Khrushchev tried to use this despicable means to brag about China's * * * production party. When Zhou Enlai expressed temporary difficulties, the Vice Minister of Foreign Trade of the Soviet Union even pointed to a large display stone in the Great Hall of the People and said, If you have nothing else to do, this will do. In order to pay off debts, on August 10, the Central Committee issued the "Emergency Instructions on the Whole Party's Foreign Trade Acquisition and Export Campaign". (Biography of Zhou Enlai, p. 1547- 1548).
