Mawangdui Boshu (silk manuscripts) calligraphy studied by Mr. Wu Wei belongs to the ancient writing that has been lost for more than 2000 years. It's a transition form from seal character to official script in Qin-Han Dynasty. It's also the source for the characters afterwards and plays a connection role in script and calligraphy history. Its artistic value is comparable with Dunhuang Mogao Cave and Qin Terracotta Warriors and Horses.

This kind of ancient writing came to light 30 years ago with the unearth of Mawangdui Han Tomb. There were only 3,300 individual Mawangdui Boshu characters unearthed. Except Tongjia characters (using one Chinese character with similar pronunciation in place of another character) and ancient characters not in common use today, there were about 1,200 common characters. After more than 20 years of study, Mr. Wu Wei dug into the law of forming the characters and "restored" the writing style in Boshu for each character. He has "restored" over 5,000 characters so far and started to compileMawangdui Boshu Calligraphy Dictionary. These are great achievements and have filled in historic blank.

On September 18, 2004, more than 20 leading Han scholars, literary history authorities and calligraphy masters from Chinese mainland, Japan, Taiwan, and Hong Kong gathered together in Pengcheng to carry out strict international demonstration and orientation on the artistic value of Mawangdui Boshu for the first time, and named the calligraphy art retrieved by Mr. Wu Wei asMawangdui Boshu Calligraphy.
