Introduction to the west gate: The first thing you see when entering the Bamboo Sea in southern Sichuan is the west gate. The west gate of the Bamboo Sea is 73 kilometers away from Yibin and 16 kilometers away from Changning County. The gate is like a piece of bamboo splitting in the middle. The four characters "Sichuan Bamboo Sea" are blended into one piece flat on the ground, and the entire gate is half-covered in the bamboo forest beside the Yujiang River.
