Pyrography (Chinese:烙画; Pinyin: lào huà) also known as "fire needle embroidery". It is said to have originated in the late Western Han Dynasty and has a history of more than two thousand years. Beijing Opera is one of China's national treasures and was listed as a national-level intangible cultural heritage in 2006.

Guo Chunlei, a Pyrography artist from Xuanhua District, Zhangjiakou City, Hebei Province, is a inheritor of the "Dao Ge Hu Lu Lao Hua" (Pyrography on a Calabash) technique, which is a city-level intangible cultural heritage in Zhangjiakou City. In his creations, Guo Chunlei incorporates the artistic style of Beijing Opera into Pyrography, creating a series of "national treasure" Pyrography works, which perfectly combine the two classic intangible cultural heritages on the calabashes, inheriting ancient techniques and promoting the excellent traditional culture of China.
