Guanshan forsythia tea has been passed down for hundreds of years, and it was famous for being a tribute to the royal family in the Qing Dynasty (1644-1911). The craftsmanship of traditional forsythia tea had been lost for many years but has now been rediscovered. 

In 2017, the traditional production techniques of Guanshan forsythia tea were palced on Shanxi's intangible cultural heritage list.
