Introduction to the Hu family's ancestral home: Although the houses in Niangziguan Village are all built of stone, the financial resources of each family can still be distinguished from the width, size, height, and sequence. Most of the villagers living here today are descendants of merchants, as well as customs guards. Therefore, several surnames such as "Hu, Yang, and Ma" have been left behind. One of the ancestral residences of the Hu family is far superior to the neighboring residences. Not only does it have a wide gate tower, but also various auspicious patterns are carved on the stone walls. The pair of stone lions in front of the door are very majestic. This house is not as spacious as the houses built by wealthy families in Shanxi, but it is fully equipped with screen walls, ear rooms, wing rooms, etc., especially the brick carvings are exquisite and delicate. The lintels of people buying and selling houses naturally have words such as "attracting wealth" and "prosperous wealth" written on them. Although it is different, it also reveals a simplicity. Perhaps this is the characteristic of Jinzhong businessmen.
