Song Gongdi
Song Gongdi became interested in Tibetan Buddhism when he grew up. At the age of eighteen, with Kublai Khan's support, he went to Sakya Temple in Tibet to become a monk. After learning Tibetan, lha-btsun translated two Chinese Buddhist works, The Theory of Hundred Fames and the Theory of Correcting the Truth because of Ming Dynasty, as Tibetan.
Later, in the third year of Yuan Yingzong's reign (1323), Song Gongdi knew his former identity, so he wrote a poem "Working in Yanjing", and wrote:
How many times did the plum blossom bloom in Lin Hejing?
guests under the golden platform should not return.
This poem fully shows his yearning for the Southern Song Dynasty, and expresses Song Gongdi's condemnation of the Yuan government's unreasonable attack on the Southern Song Dynasty, thus violating the literary inquisition. Later, when the Emperor of the Yuan Dynasty discovered it, he was furious and ordered Song Gongdi to die. He died at the age of 53.
As for Song Gongdi's ending, there is a sentence in the Chinese "A Collection of Buddha's Past Dynasties": "In April of the third year of Zhizhi (1323), the Duke of Ying was given the honour to die in Hexi, where he summoned a monk, Confucianism, and collected scriptures."
