In the Kamakura era, The Unknown Grass Son and The Old Story recorded Shao Qing Yan Na's life after he was down and out. Among them, Strange Tales from a Lonely Studio describes her as a "ghost-shaped mage" when she became a monk, which shows her loneliness and desolation. What is even more deplorable is that it is said that in the first year of Kuanren (A.D. 10 17), when her brother Qingyuan sent a letter and was killed by Yuan Lai's relatives, she was implicated and finally forced to prove her daughter's identity by uncovering the curtain.
Perhaps it is because Shao Qing Yan Na became a mystery after he left the palace that many legends about Shao Qing Yan Na were circulated in Japan. Many people believe that the literary work Matsushima Diary [8], which was circulated in the middle of the Kamakura era, was written by Qing Shaoran. However, according to the textual research of the famous Sinologist Ben Ju Xuan Chang in the Edo period, this Songdao Diary should be a fake book written by later generations in the name of Qing Shaoran.
