There is a danger that "one man can guard the gate, but ten thousand men cannot open it", and it is majestic. The existing village gate is 2.45 meters high and 2 meters wide, with the words "Blessed Land Immortal Pass" written across the forehead, and a couplet on both sides: "Cadastral clouds and rocks form a guarantee, and natural stone walls separate the beacon smoke."
