The Central People's Government invited the Tibetan authorities on several occasions and through many channels to the negotiation table. With the approval of the CPC Central Committee, on February 25, 1950, the Southwest Bureau of the CPC Central Committee asked Mi Wu, a well-known Han monk from Sichuan Province, to travel to Tibet for mediation. The eminent monk had lived in Tibet and Tibetan areas in other parts of China for 20 years and was a close acquaintance of members of the Tibetan upper class, including Lhalu. Charong and Yutog. Having studied for 10 years at the Zhaibung Monastery, he was granted the highest academic degree of the Yellow Sect-Lharangba Gexi. 　　The goal of his Tibetan trip was to explain to his friends the Central Government's policy for negotiation with the Dalai Lama on matters concerning the peaceful liberation of Tibet and the firm determination of the Central People's Committee to deploy PLA troops in Tibet. During his visit, he spoke with members of local government of Tibet led by the Dalai Lama and did his best to persuade the Dalai Lama to break with the American and British imperialists and to return his allegiance to the motherland. He told the Dalai Lama that he or his representatives were expected to go to Beijing for negotiation with the Central Government or negotiate with the PLA Front Headquarters. Mi Wu did a great deal in this regard and also aided the PLA troops in acquiring food and shelter when they marched into Tibet.
　　In January 1950, the Northwest Bureau of the CPC Central Committee sent Zhang Jingcheng and some others to Tibet with a letter for the 14th Dalai Lama and Prince Regent Dagzha from Liao Hansheng, then Vice-Chairman of the Qinghai provincial government. He also conveyed the oral message of Master Xerab Gyamco, also a vice-chairman of the Qinghai provincial government. Attaching much attention to Liao's letter, the local government of Tibet discussed it in the Tibetan Assembly and responded saying, "After receiving your letters of January 27, 1950, we immediately translated them into Tibetan and read them before the Tibetan Assembly. We understand your plan to liberate Tibet within the year and your hope that we are not cheated and induced by the imperialists of Britain and the United States. We cherish the long-term and friendly relations between the patrons and the monasteries. Please explain to Beijing that everything is very clear, we are looking forward to your instructions."
　　On May 3, 1950, the Qinghai provincial government sent a delegation composed of lamas to Tibet to explain the principles of the Central Government and to persuade the Tibetan government to accept the conditions for peace talks, and immediately send representatives to Xikang to negotiate with the PLA. The delegation was led by the Living Buddha Damcai Tubdain Qumqi Norbu, elder brother of the 14th Dalai Lama. As the abbot of the Tar Monastery, he was a member of the Northwest Ethnic Affairs Committee. The deputy leader of the delegation was Living Buddha Xanlin Geden Gyamco. Members of the delegation included Xarabcang, the 7th Living Buddha of the Longwo Monastery, with a religious position higher than the Living Buddha Damcai. Chi Yurui served as the secretary of the delegation. Starting in mid-July 1950, the delegation arrived at Xaquka Village in Nagqu Prefecture in northern Tibet on October 14, where they were stopped by Tibetan government official Kamqoin Tubdain Sambo. According to the instructions of the Tibetan authorities, the delegation traveled to Lhasa in two separate groups. However, Xarabcang, Xanlin and another delegation members were placed under house arrest soon after they reached Lhasa. Chi Yurui and three others were sent to Nedong under escort and put into custody. The Living Buddha Damcai traveled to Lhasa and then to Yadong, where he met with the 14th Dalai Lama before fleeing to India via Yadong.
　　Secretary Chi Yurui struggled with Kamqoin Tubdain Sambo, who was in charge of their imprison. Since the Tibetan authorities had sent deputies to Beijing, they reasoned, the Tibetans would have to let Chi Yurui go to Lhasa. When released, they hurried to Lhasa and began their work. They overcame numerous difficulties in keeping in touch with Beijing and avoiding supervision and obstruction by the local government. In August 1951, they finally finished the historic task.
　　On July 10, 1950, the Living Buddha Geda of the Baili Monastery in Garze County, member of the Southwest Military and Political Committee and vice-chairman of the Xikang provincial government, was dispatched to Tibet. Re set off from the Baili Monastery with a letter from the commander-in-chief of the Southwest Military and Political Committee. On the way to Tibet, he spoke with locals and monks he met that the Central Government and the PLA allowed freedom of religious belief, protected monasteries, respected the customs of the ethnic minorities, and planed to improve living standards in the border regions; the Central Government allowed the Tibetan political system to remain unchanged and that all matters related to reforms in.
　　Tibet would be decided by the Tibetan leaders and the Tibetan people through consultation. Re also dissuaded the heads of monasteries and local militias from taking a hostile attitude toward the PLA and suggested that the Han and Tibetan people should unite. His actions won the support of the monks and people he met, but also aroused the hatred of the imperialists and collaborators. Arriving at Qamdo on July 24, he explained the aim of his trip to Lhalu Chewang Doje, the chief attendant of Qamdo, and wrote to his good friends, telling them he would go to Tibet to mediate a peace settlement. Learning the news, the Tibetan authorities detained him in Qamdo, not allowing him to go further into Tibet nor to return.
　　The plot of detaining Geda was hatched by the British spy Robert W. Ford and his accomplices. On August 1 3, they forced Geda to drink poisoned tea. 'I'll not regret even if I die. All I wish to do is to go to Lhasa and meet with the Dala Lama," Geda said. On August 21, Geda was forced to drink a poisoned tea again. and on August 22, Geda died in his basement cell. To hide the evidence, the group burned his body and escorted Geda's entourage into Lhasa. After the liberation of Qamdo, Ford was arrested.
On May 9, 1950, Xerab Gyamco, Vice-chairman of the Qinghai provincial government who enjoyed high prestige in Tibet, addressed the 14th Dalai Lana by way of a radio broad-cast in an attempt to persuade him not to believe rumors and to send a delegation to Beijing t;()r peace negotiation. However, the Tibetan authorities turned a deaf ear to the broadcast.
