Tour guides worry that braiding will delay your trip, or braiding may take up too much shopping time and affect your income. I have also studied this matter specially. No matter where in Yunnan, no matter which nationality, there is no such statement at all. This braid is the most common among Tibetans and is woven by Naxi, Bai, Yi and Hani. Before hairpin became popular, it was used to fix headdresses. If you don't believe me, you can look at the makeup photos taken during the census after the founding of the People's Republic of China. This braid is very common.
