Introduction to "Fang Gaosheng": "Fang Gaosheng" is a folk festival entertainment activity of the Dai people. It uses a whole big bamboo and fills the bamboo joints with gunpowder. After igniting, the whole big bamboo can collapse hundreds of feet into the sky. Become a veritable "high rise". The big "Gaosheng" weighs tens of kilograms and is 7-8 meters long, while the small one weighs a few taels and is more than 1 meter long.
