Why is "Guizhou cuisine" trending?

Wikipedia Overview

Guizhou cuisine, or Qian cuisine, consists of cooking traditions and dishes from Guizhou Province in southwestern China. Guizhou cuisine shares many features with Sichuan cuisine and Hunan cuisine, especially in bringing the sensation of spiciness and pungency. What makes Guizhou cuisine unique is the emphasis of a mixed sour-and-spicy taste, as compared to the numbing-and-hot sensation featured in Sichuan cuisine and the dry-hot taste featured in Hunan cuisine. There is an ancient local saying, "Without eating a sour dish for three days, people will stagger with weak legs". The saying reflects how Guizhou people love local dishes with a sour taste. The combination of sour and spicy flavours is also found in Shaanxi cuisine. Guizhou cuisine differs from Shaanxi cuisine in that it lacks the emphasis on the salty taste, which is a common trait found in most northern Chinese cuisines. In addition, the unique sourness featured in Guizhou cuisine comes from the local tradition of fermenting vegetables or grains, and not from using vinegar products.
