"Family guidance and instruction" can also be found in the courtyard dwellings of Dang Jia Cun, which feature rich contents and are very well preserved. Instructions about learning or frugality can often be found on the screen wall right opposite to the entrance gate or on the walls of the hall, which continue to benefit and encourage modern people.

In Dang Jia Cun, brick, wooden or stone carvings can be seen almost everywhere. Brick carvings are used to decorate the lanes, the doorways or the screen walls . Wooden carvings are often found on windows, doors, gateways and furniture, while things made of stones, such as memorial arches, horse-mounting stones and tethering stakes, were usually carved with care and precision.

It is very surprising these courtyards can be found on the Loess Plateau. What is even more astonishing is that they are preserved so well. Why? According to the elderly people in the village, this is partly because of the wood-framed architectural structure, which is solid and strong to such an extent that even if the walls fall down, the frame structure will not collapse.

Another important factor is the villagers' awareness of preserving these buildings, which they say is a village tradition. In the past, if a family suffered a money shortage and they had to sell the house, they had to sell it to a Dang or Jia family rather than to outsiders. Also, the facilities once used for preventing bandits from intruding played an important role in the preservation.

Every year, there are people who get married and who would like to build new houses. However, these houses cannot be built within the village but on a terrace to the north of the village, which they call the "new village".

Thanks to the villagers' tremendous efforts, people of today can still walk around the time-honored village and feast their eyes on the ancient Chinese civilization while enjoying the unaffected and simple customs and morals of the local people.
