With the vicissitudes of time, the Jiuyan Tower has lost its defensive function as a watchtower. On the top of the Flaming Mountain, the Jiuyan Tower has experienced hundreds of years of wind and rain, the bricks and stones slowly fall off, and the walls gradually collapse. Since 2000, the cultural relics departments of Beijing and Yanqing District have invested more than 21 million yuan in archaeological excavation and emergency repair of Jiuyan Tower and its military camp site, basically eliminating the danger of Jiuyan Tower and its military camp site. In 2000, Sihai town invested in cleaning up the surroundings of Jiuyan Tower and unearthed more than 10 inscriptions on the Great Wall. In 2005, the cultural relics department carried out emergency repair on the body of Jiuyan Tower.

It revealed a large area of associated building base sites, cleaned up the Temple and the North watchtower. The actual excavation area was more than 1600 square meters. More than 500 pieces of door plaques, weapons, stone tools, porcelain and various building components were unearthed, and the site was protected.
From 2013 to 2017, Beijing Municipal Administration of cultural heritage implemented the emergency repair project of the Great Wall which contains Jiuyan Tower (No. 108-110 watchtower) and the Military Camp site protection project of Flaming Mountain. The implementation of these projects has created favorable conditions for the protection and utilization of the Jiuyan Tower.
Recently, the emergency reinforcement project of the North platform of Jiuyan Tower and the west wall of Military Camp was completed. The project lasted more than three months. and a total of 20 meters long, 5 meters wide, 5 meters high wall repair work and 32 square meters platform area collapse repair work. A total of 20 meters long, 5 meters wide, 5 meters high wall, and a 32 square meters platform area collapse repair work has been completed.
In the past 20 years, the cultural heritage sector has never stopped repairing the Jiuyan Tower and its Military Camp. Nowadays, climbing to the Jiuyan Tower, the Tower stands tall, the wind whistling through the arrow window. Overlooking the verdant mountains, the Great Wall stays ups and downs along the mountain, the feeling of vicissitudes of life arises naturally. The tower, which has stood for more than 500 years, silently tells of the diligence and wisdom of the laboring people in ancient China.
The steep walls lead straight to the site of Military Camp. The site has an irregular rectangular plane. The west wall is about 100 meters long, the north wall is about 45 meters long, and the south wall is about 50 meters long. The camp covers an area of about 2,500 square meters, all of which are built of rubble and stone. There is a gate on the wall of the north city.On the gate, there is a tablet inscribed with two characters, wai Yan, inscribed in regular script. The upper part is hu Li, the imperial envoy huailong soldier Anchashi, and the closing is the words "Autumn Auspicious Dan, The fifth day of Wanli (1618). Today, only the base of the camp is left, and the living pattern of the soldiers guarding the border hundreds of years ago can be faintly discernable from the cornerstones.
