The Luocheng mountains and rivers in northwest Guangxi are beautiful, the forest is deep, the wonders are endless, and the Qing Dynasty Kangxi emperor is known as the "the world's cheap first" in Chenglong. Yu Chanlong wrote to his friend Jing Xuetao in the letter said Luocheng "mountain like a sword row, water like soup boiling", and complained: "wail! Hu why come to the squat?" However, the Yanlao people living here seem to be particularly fond of the place. The Yanlao people flourished among the mountains, cultivated and harvested, created the richness of this land with hard work and wisdom, and told the history of this land with simple mountain songs and beautiful legends. In Luocheng, you can hear many stories and legends about local mountains and caves, such as Kenwang Mountain, Phoenix Mountain, Chengguangdong, Yanniangyan, etc. The legends cover the ghosts and magical works of nature with a mysterious and mysterious veil, which makes people yearn for. When I was a child, I heard the old man tell the ancient (story), and I often thought that I had the opportunity to go to these mountains and caves to go exploring and seeking the secluded, looking for the legendary miracles and immortal marks. Tianmen Mountain Scenic Area is located in Yuanmengtun, west of Huaiqun Town, Luocheng County, about three kilometers away from Huaiqun Town. Tianmen Cave is more than 100 meters high and 30 meters wide. It is magnificent and beautiful. The rock wall is smooth and like a sharpener, like an ax. Look at the sky door from a distance, like a stage that opens the curtain, and like an open door. The clear Jianjiang River passed through the Tianmen, the river was clear to the bottom, and the green bamboos on the bank were reflected in the river. The Tianmen Cave was clear, cool and cool. The rock top was arched and arced, and all kinds of stalactites were hanging from the rock top. They were strange and varied, and they were lifelike and amazing. There were poets who traveled through Tianmen Mountain and praised the inscription: ghosts and axes, a hole door, more charming paintings in the painting; light boats first tried the Jianjiang warm, the riverside Xinxu drunk spring. According to ancient times, Jianjiang often rose, flooded, and the people could not settle down. The mountain god Glailei saw innocent people suffering from the flood, regardless of the demons' obstruction, came forward, chiselled the mountain day and night, finally broke through the cave, let the river pass through the mountain, so there was a heavenly gate.
