History.
Funeral Notes is one of three kinds of notes written by Wang Xizhi, including two kinds of thank-you notes and German notes, which are collected in the Sanzhiwan Museum of the Japanese Imperial Palace. By the time it was exhibited in Shanghai in 2006, Funeral Notes had existed in Japan for more than 1000 years and had been hidden in the palace. There are three seals of Zhu Wen's "Li Yan" on the burial post, which is equivalent to the period from Tang Dezong, China (the third year of Tang Jianzhong in 782 AD) to Tang Shunzong (the year of Yongzhenyuan in 805 AD). It can be concluded that it was introduced to Japan from the Tang Dynasty.
In the early years, funeral notes flowed into Japan, which was related to the historical event that Japan sent envoys to the Tang Dynasty. The history of "sending envoys to the Tang Dynasty" flourished in the fourth year of Zhenguan in the Tang Dynasty (AD 630) and ended in the first year of Ganning (AD 894). During this period, ambassadors, deputy ambassadors, festival ambassadors, judges, painters, doctors, monks, overseas students and other people with status and skills were sent, totaling more than 5,000 people in 20 batches, and the exchange lasted for more than 260 years.
Another view is that when Jian Zhen (688-763 AD), a monk of the Tang Dynasty, was invited to travel eastward. But from the time point of view, although it is not contrary, it lacks accurate and credible basis.
Since "Mourning Post" came to Japan, it has not been recorded. In the 18th year of Guangxu reign of Qing Dynasty (A.D. 1892), Yang Shoujing, a calligrapher of Qing Dynasty, was searching for ancient books in Japan. After re-tracing and sketching, it was compiled into the book Neighbourhood Yuan Tie in the 19th year of Guangxu in Qing Dynasty (1893).
1936, the memorial post was recorded by Rong Geng's Shadow of Two Kings.
