Visits Return to the city site scale Jiaodong Peninsula first I heard that the city of Longkou had a site to return to the city and Lai Ziguo. On June 17th, the reporter drove several hundred kilometers and came to the city of Longkou (formerly Huang County) 15 miles southeast of Huali. Although the villagers here know little about Lai Ziguo, they are very familiar with the ruins of the ancient city. In Jiangjiacun, the hometown of Laishan, there is a small basin surrounded by hills. The ridges along the periphery of the basin and the remnants of the old city wall intermittently draw the contours of an ancient city. This is what many scholars think of Laiguo. Gudu - the ruins of the city. In addition to the outer city built along the ridge, there is also a strong inner city. The remaining 60-meter-long, 10-meter-wide, and 6-meter-high earth platform in the southwestern corner of the city is still looming after thousands of years of wind and rain. Can see the majestic city. The ancient city site is a national key cultural relics protection unit, and the stone tablet is engraved with the words "return to the city site." “The ancient city wall was more than 10 years long. Now it is only a few days.†Jiang Dan, a villager in Jiangjia Village, said that her family lived at the foot of the city’s city wall and could see the ancient city every day. As a child, her mother often took her to the ancient city wall to play. The villagers under the city often find pottery and bronze wares in the farmland. On one occasion, she also found a copper spear in the ground. Liu Yutao, deputy director of the Longkou City Museum, said that the ancient city of Guicheng has two inner and outer cities, and the outer city has irregularly shaped city circles along the hills surrounding the basin. The city includes Caojia, Nanzhao, Jiangjia, Dongheping, Dongjia, Chijia, Beishan, and more than 8 natural villages. The village names are often referred to as "returning to the city." Due to long-term natural and man-made damage, most of the walls have disappeared. The scale of Guicheng ruins is currently the first in many ancient city sites on the Jiaodong Peninsula. Most archeologists believe that returning to the city should be an ancient country. Many cultural relics unearthed in the area of ​​the city have provided important evidence for the country’s level and national status.
