Legend of the Old Woman Of Lishan
The Old Woman of Lishan is an ancient Chinese go legend that dates back the Tang Dynasty. Liu Zhongfu?, a national imperial champion of the era, supposedly encountered an old woman in the countryside of Mount Li (Lishan) who defeated him in 120 moves. There is a famous kifu attributed to this legendary event called "Blood Vomiting Kifu" and it is seen on the Chinese Wikipedia on the "History of Go".
According to legend, Wang Jixin also supposedly encountered an old woman in Lishan as well.
