Huang Longshi, a Chinese guoshou of the 17th century, is widely regarded as one of the most accomplished go players in history. This tournament is named after him because it is held at Jiangyan, a small town in Jiansu province of China, known as Huang's hometown. The tournament was first introduced in 2011 as an international women's team tournament. In 2012 it became a win-and-continue team tournament for the three major Go-playing countries - China, Japan and Korea - apparently to replace the defunct Jeongganjang Cup.
Chunlan Cup World Professional Weiqi Championship (春兰杯世界职业围棋锦标赛) is the first major international Go tournament organised by mainland China. It is named after the main sponsor Chunlan Corporation, one of the 50 large Chinese enterprises and best known for its air-conditioning products. Since term 3, the tournament has been held once every two years. Early rounds are often hosted at the city of Taizhou in Jiangsu province where Chunlan's headquarter is based.
