On April 15, 2024, in Mojiang Hani Autonomous County, Pu’er City, Yunnan Province, local people celebrated the International Twins Festival and the Hani Sun Festival.

According to the filmer, Mojiang is the only autonomous county of the Hani ethnic group in China, renowned as the "Hani Homeland" and the "Land of Twins". Every May Day, the International Twins Festival is held, where twins from all over the country gather in Mojian to celebrate together. One of the distinctive activities is "smearing faces", where participants rub black soot from the bottom of a pot onto each other's faces, symbolizing the transmission of blessings.
