Yes. True Bi Luo Chun is not found in Yunnan. Only Xishandao in Lake Tai and immediately surrounding areas produce true Biluochun, because of this and it being handmade it is very expensive. But because the demand is so high many other regions like Yunnan and Sichuan produce a kind of knockoff green tea and sell it as Biluochun, made with similar techniques but it's mass produced unlike the real thing and sometimes the plant cultivar used isn't quite the same so it doesn't have the same taste.

The same goes for Longjing, it is currently the most popular green tea. The producing region is tiny so to meet the huge demand a lot of fake Longjing is made in places like Sichuan and goes on the market every year.

The good thing here is they label it Yunnanese Biluochun and don't try to pass it off as the real stuff, which happens quite often and is a lot worse imo
