Are there any original works by Wang Xizhi in the existing works?

At present, the original "Funeral Signs" in Wang Xizhi's calligraphy is circulated in an orderly way. They were brought to Japan by Du Dong in Jian Zhen, and are considered as one of the most important works of Wang Xizhi. Funeral Notes consists of 8 lines and 62 words. The brushwork is exquisite, and the structure is mostly sideways, which is strange and unique. After careful examination, it is found that the font is different from the fluency and integration of Lanting Preface. "Mourning Post" is currently in the Palace Office in Japan (responsible for managing the affairs of the Palace Office).
