XX《绥中老照片》In the book, taken in the 1970s, only a pile of loess appeared. In the media and on the Internet, I also saw the words "avant-garde is a Tucheng". In fact, it is not true. The avant-garde ancient city is filled with loess. The inner wall, the outer wall and the horse road are all made of large bricks and paved. It is a complete and solid military ancient city. The disappearance of the ancient city is closely related to the rise and fall of the former defenders. Perhaps it is the baptism of war, and it may be more man-made destruction. The big blue bricks on the ancient city disappeared, and even the loess in the heart of the wall was gone. The ancient city site became a flat land without any traces.
In the 50s and 60s of the last century, the large bricks were always seen on the walls and walls of the old houses around the avant-garde town. There are whole, half, and the old people say that it is the inner wall of the ancient city and the bricks on the outer wall. There are also large bricks that are as hard as stones. The old man said that it is a steel brick for paving roads. Those bricks don’t know how many times they have been used repeatedly by locals. After the popularization of Beijing cottages in the 1980s, the change of building materials and the improvement of the quality of houses, the large blocks of bricks were almost extinct in the avant-garde town.
When the water was launched in 1959, the ancient city site on the southeast side of Qianwei Town was the highest point on one side, and the moat (original site) on the east side had been dull. Hundreds of thousands of victims, including the author's family, crowded the rectangular loess bag of the east and west.
In the fall of 1968, the second production team of the Guta Brigade was to store the sweet potato seeds, and arranged for the members to dig the mantle in the ancient city site. The author is one of the excavators. We found that the loess there was very solid. Although the mantle was dug up like a tunnel, the soil layer did not collapse, and it was stronger than the natural soil. When cleaning the side of the house, the silver ornaments that the ancients had fallen were also found.
