Luolong Village in the mountains of northwestern Hunan is backed by Yinlong Mountain, which hides the tombs of the former vassal kings. The villagers rely on the mountains to eat and drink, but they guard the taboos engraved in their bones and blood. The mountain climbing team in the village is not an ordinary mountain team. They are mountain guardians passed down from generation to generation. They understand folk feng shui, know the layout of the yin houses, and guard the taboos in the mountains. They also have the secret ability of "exploring the tombs in the mountains". A hundred years ago, in order to protect the village and save famine, they broke the taboos and entered the ancient tombs of Yinlong Mountain to obtain treasures. Since then, they have become the "living lock" of Yinlong Mountain. While guarding the Feng Shui of the ancient tombs, they stopped outside tomb robbers, and they also guarded the village's thousands of folk taboos in northwest Hunan.
The taboos of Luolong Village are all connected with the Feng Shui of Yinlong Mountain. No umbrellas are allowed in the hall, no whistles are played at night, no home is allowed, and pregnant women are not allowed to enter the forest. These rules are not superstitions, but are warnings of backlash from the Feng Shui bureau of the ancient tombs. Once broken, strange things will happen in the village.
