Yongbulakang, meaning "mother's womb" in Tibetan, is the first palace in Tibetan history and one of the earliest buildings in Tibet. It is located in the southeast of Zedang Town, Shannan Prefecture, and towers on the top of Tashi Ciri Mountain on the east bank of the Yalong River. . According to legend, it was built by Yongzhongben believers in the 2nd century BC for the first Tibetan king Nietri Zampu. It later became the summer palace of Songtsen Gampo and Princess Wencheng in Shannan. It was changed to a Huangjiao temple when the fifth Dalai Lama came. Yongbulakang mainly enshrines the statue of Sakyamuni Buddha. The murals in the palace vividly depict the historical stories of Tibet's first king, first building, and first piece of cultivated land. Yongbulakang is divided into two parts. The front part is a multi-story building, and the rear part is a square high-rise watchtower connected to the front part. In the 5th century AD, during the reign of Tibetan King Tuotuo Nianzan, it is said that a Buddhist sutra fell from the sky and happened to fall on the top of Yongbulakang Palace. No one could recognize it at the time. Some sages asserted that someone would be able to interpret this book by the 7th or 8th century AD. So this book is well preserved in Yumbulakang.

Yongbulakang is said to be the earliest building in Tibet. It was not a temple at first, but the palace of the leader of the early Yarlung tribe. Folk legend goes: "The palace is not earlier than Yumbulakang, the king is not earlier than Nietri Zanpu, and the place is not earlier than Yarlung." Yumbulakang is the palace built by Nietri Zanpu in Yarlung.

"The Records of the King of Tibet" records: When the first generation Zanpu Nie Tri Zanpu descended the ladder and walked to the Simen Plain of Zantangkuang, he was seen by twelve talented Yongzhongben believers who were grazing there, and asked him where he came from. Come? He pointed his finger to the sky to indicate his answer. They understood that he had come down from heaven, which meant that he was qualified to be the king of Tibet. So they used their shoulders as his throne and lifted him high. When he got up and went to the city, everyone called him Nie Chi Zanpu (meaning King on the Shoulder Seat)." This is the same thing as Trizan Po'ade mentioned in "Qing History".

When Nie Chi Zanpu built Yongbulakang, he also interpreted the "Xin Family's Hanjia Dharma" in Yongzhong's Benji. In turn, according to Puba Sangye Gyatso's calendar calculation, Nie Chi Zanpu came to Yalong in the year of Muhu (127 BC), so the founding of Yongbulakang was more than 2,100 years ago. years of history. When Nie Zan, the twenty-eighth generation Zanpra Tuotuo, was in power, in the Year of the Water Snake (446 AD), "from the roof of the Yongbulakang Palace, the "Hundred Prayer Supplementary Evidences and Repentance Sutra" and the golden Pagoda, "The Six-Character Mantra of the Heart of the Mahayana Precious King Sutra", "Jidamani Dharma Door", etc., and also issued a voice from the air saying: 'If it is passed down to five more generations, the meaning of these sutras will be known.'" The fifth generation Zanpu after Latuo Tori Nezan was Songtsen Gampo. It is said that Songtsen Gampo built two-story palaces on both sides of the original palace. The ground floor of the hall is the Buddha Hall, and the second floor is the Dharma King Hall. At this point, Yumbulakang was converted from a palace into a temple. Later, there were expansions in all dynasties, and gradually a foyer was built on the west side of the hall and a monk's room was built on the south side. During the reign of the fifth Dalai Lama, a four-cornered gold roof with spires was added to the watchtower-style building. In the 15th century, Tsongkhapa disciple Kezhu Dundup founded Riwu Qulin in Qihuali north of Yongbulakang, and the temple began to manage the affairs of Yongbulakang. Five lamas were sent to Yongbulakang every year, rotating once a year, and each lama was given ten grams of highland barley per year until before the democratic reform.
