Charong Dasang Zhamdui was a son of an arrow-making artisan living in Pengbo in the northeast of Lhasa. To avoid heavy corvée labor, he was sent to the Sera Monastery to become a monk. He served as an attendant for a monk official and later as a gardener in the Norbu Lingka, planting trees and flowers. When the British troops occupied Lhasa in 1904, the 13th Dalai Lama, escorted by some officials and retinues, fled to the hinterland at night. Charong, as a member of the retinue, was very intelligent and attended upon Dalai painstakingly. The latter liked him very much and appointed him as his valet. After arriving in Urga, Outer Mongolia, Charong learned to speak Mongolian fluently. He not only conducted affairs wisely, but also acted as Tongsi (interpreter) for the Dalai and became indispensable to him.

After the Revolution of 1911, Lhasa descended into chaos. Galoin Charong Wangchog Guibog and his son were put to death in 1912. The following year, the 13th Dalai Lama returned to Lhasa. Hearing of the tragedy of the Charong family, he showed his sympathy. He decided to let Dasang Zhamdui become the husband of the Rinzin Qoizin (senior Charong's daughter-in-law) and live with her family. How can wise and fine-looking Rinzin Qoizin of noble birth, have a liking for a minion? She never agreed, but she could not directly challenge the order of the Dalai; instead, she declined the proposal under the pretext of becoming a nun. In order not to incur the displeasure of Dasang Zhamduie, she put forward a view to the satisfaction of both parties that he could marry the senior Charong's eldest daughter Bemar Zholgar. In addition to owning land and subject people, aristocrats had the right to secure an official position. Dasang Zhamdui came from a poor family. According to tradition, the common people had no opportunity to enter an official career without first joining the aristocracy. Because of the favors bestowed on him by the Dalai, Dasang Zhamdui became the son-in-law of the Charong family, lived with them and became the family heir. Then, he saw rapid advancement in his official career. Before long he was promoted as the commander-in-chief of the Tibetan Army, and subsequently appointed as the Galoin and Silun of the Gashag government. In those years, Dasang Zhamdui was second only in power and influence to the Dalai Lama. After the senior Charong died, the original great aristocratic title actually existed in name only, as the family had huge debts and nothing apart from an old residence. Dasang Zhamdui had to rejuvenate the family fortunes. He had little education but was a commercially-minded person able to make money. Relying on the authority of his office, he borrowed money from the finance bureau of the local government, sent his trusted aides to sell Tibetan wool and quviut in India and carry back a lot of gold, silver, silk and woolen goods. He set up stores in Chengdu, Kangding, Xining and Dali to sell Tibetan specialties and goods exported from India, and at the same time established stores in Lhasa and Xigaze to sell porcelains, silk and tea from the hinterland. He sold the old residence of the Charong family on Barkor Street to newly-rising plutocrat Bamdachan, purchased a lot at the Shazha lingka, and built a magnificent three-storied house. A beautiful garden was built respectively on the eastern and western sides of the house, in which a western-style villa was constructed.

He also utilized the marriage connection to develop nepotism along with other upper class families. After marrying the eldest daughter of the Charong family, he soon arranged the wedding of the pretty second Charong daughter to Zhasa Horkang Pengcho Wangchog , an aristocrat; the third daughter Tsering Yuzin to the second son of Deleg Rodain, a great aristocrat in Xigaze; sent the fourth daughter Rinchin Chomar to Darjeeling in India to study and she married the great aristocrat Cherin Jigmei after graduation. When the second daughter Cedain Zholgar married old Horkang, she was only 16. Subsequently, she gave birth to a son named Horkang Soinam Banba who later held the post of vice-chairman of the CPPCC Tibet Autonomous Region Committee, and a daughter who later married Nedoi, an aristocrat in Gyangze. However, Zhasa Horkang did not enjoy good health and passed away when Cedain Zholgar was only 24. Dasang Zhamdui shifted his love to this fine-looking young widow. He often went to the family and cohabited with her on the pretext that he needed to look after her daily living needs. They had six children. Dasang Zhamdui thus became the husband of the two sisters of Charong. In old Tibet, there was a marriage custom of brothers sharing a wife and sisters sharing a husband. Therefore, this behavior of Dasang Zhamduie was not that unusual. However, the raising of six children in the Horkang family was a heavy financial burden. In the aristocrat family, each child needed a servant and nursemaid; later there would be a dowry when a daughter wed. Although having a high reputation in Tibet, the Horkang family was in poor financial shape. After growing up, the eldest son, Horkang Soinam Banba, began to take charge of the domestic economy. He could not dispute with his mother, so he filed a suit against Dasang Zhamdui with the Gashag government. Dasang Zhamdui had no choice but to take his own children back to the Charong family for support. His wife, Bemar Zholgar, was sterile, so the children became the descendants of the Charong family reality.

Later, his eldest daughter Tsering married the Bhutan Prime Minister Jigmei Dorje; his second daughter Dege Chomar Rosi Punkang Tsering Toinzhubp; his third daughter Soinam Chomar, Kashod Toinzhubp; his fourth daughter Tsering Chomar the eldest son of Living Buddha Deom; his fifth daughter Toinzhubp Chomar Shokang Tubdain Nyima; his youngest son Pungco Gyaincain served as a member of CPPCC Tibetan Committee in the 1980s.

Charong Dasang Zhamdui later suffered a setback in his official career. He was first removed from the post of commander-in-chief of the Tibetan army and then edged out of the Gashag government. He lost his main backer when the 13th Dalai Lama passed away, and could not recover his old political clout. However, his wealth was still considerable, and with numerous relatives by marriage, he did not feel lonely.

Unlike the common people, Tibetan aristocrats wore luxurious clothes. Their jackets had long sleeves, indicating that they never did rough work that was left to their underlings. Although Charong Dasang Zhamdui, who was born into such a family, was very rich and noble, and served as senior official and businessman, he still liked manual labor. He formerly acted as a gardener, so he spent more time in cultivating flowers, grass and fruit trees in his leisure time. In the 1950s, many species of grass and flowers in Lhasa were named "Charong", such as Charong rosebush and Charong rose. He also set up a vegetable garden in his villa by the Lhasa River, spent more money in purchasing glass to build a greenhouse, and introduced vegetable seeds from foreign countries. After harvesting, he immediately sent his servant to present a species of cauliflower as a gift to his children and relatives by marriage. Although Garshopa, father-in-law of his daughter, once served as high official, he never saw such a plant. He wrote a letter to Charong Dasang Zhamdui to inquire: 'I have received your gifts and extend my appreciation to you, but I want to consult you about this gift. Is it a flower or vegetable? If it is vegetable, could you teach me how to cook it?' After receiving this letter, Charong Dasang Zhamdui sent a chef at once to show him how to cook it.

Charong Dasang Zhamdui followed the upper-class reactionary clique to participate in the armed rebellion in 1959 and served as the deputy commander of the armed rebel headquarters. He was captured in the Potala Palace on March 22, 1959 and died in the prison before long.
