The sun shines brightly, and the eagle spreads its wings. The spring scenery on the plateau is infinitely beautiful, how can I not sing... - "Turning over the Serf Sings" - Guimao Spring comes, the grassland at the foot of Everest begins to turn green, the weeping willows along the Lhasa River change into new clothes, and the peach blossoms of Linzhi bloom brightly. In a vibrant landscape, the people of all ethnic groups on the snowy plateau are celebrating another anniversary of the liberation of millions of Tibetan serfs. On March 28, 1959, under the leadership of the CPC, a democratic reform centered on the abolition of the feudal serfdom, which integrated politics and religion, was launched in Tibet. The snowy plateau bid farewell to the old system and entered a new era in history; Millions of serfs have been completely liberated and become masters of their own destiny, realizing their right to be human beings and enjoying the civil rights prescribed by law. 64 years ago. From bitter to sweet, the snowy plateau has changed into a world of thick land, which has been plowed deep furrows by agricultural machinery. The wrinkled corners of the eyes of the 78 year old Daguojie smile, saying, "This year is another good time." Daguojie's home is located in Jiadui Village, Jiangre Township, Jiangzi County, Shigatse City. With the vigorous promotion of rural revitalization in recent years, the village has taken on a new look, with distinctive Tibetan style new houses, hardened village roads, flat and open, and complete public facilities. "I grew up here and have a deep affection for the land. Every year, I plant seeds in the field and wait for the crops to mature into grain. My heart is very secure. In old Tibet, everything that grew on the land had to be taxed by the serf owners, and I was afraid of hardship." In memory, Daguojie's thoughts floated back to the days when he was a former serf. In the area of Jiadui Village, it was the manor of the serf owner in the old Tibet period - "Yaxi Pingkang Manor". The serfs of old Tibet were divided into three types: poor, heaped poor, and Langsheng. At that time, the "three lords" (officials, nobles, and monks from the upper echelons of monasteries), who accounted for less than 5% of the population, occupied almost all of Tibet's wealth, while serfs and slaves, who accounted for 95% of the population, struggled to survive. "The old Tibet was inhumane, and at that time the lords were even more ruthless towards serfs than cattle," recalled Daguojie. One autumn, the serfs gathered highland barley for the lord day and night, and the 8-year-old Daguojie was responsible for cooking tea for the overseer's butler. As the water was not hot, the butler casually picked up a stone and threw it at Daguojie's head. In an instant, he bled continuously and fainted to the ground. The cruel blows that Daguojie suffered were deeply imprinted in his childhood memories, which were also painful memories that the dark and cruel feudal serfdom had branded on that generation. "At that time, every night when we looked at the sky, we felt that we suffered more than the stars in the sky. When would this dark night end?" said Daguojie. In March 1959, the local government of Tibet and the upper reactionary groups launched an armed rebellion. The CPC followed the historical trend and the wishes of the Tibetan people to quell the rebellion, and led the people of all ethnic groups to carry out democratic reforms
