Tobu Castle: Present-day cities. In the early years of the Western Han Dynasty, it was called Dongwu, and the Sui Dynasty was renamed Zhucheng, and the Song, Jin, and Yuan belonged to Mizhou. The Ming and Qing dynasties were called Zhucheng. After the founding of the People's Republic of China, Zhucheng County was established, and the county was withdrawn in 1987 to establish a city.

Anqiu: Anqiu City, located in the middle of the Shandong Peninsula. The history and culture of Anqiu can be traced back to the Spring and Autumn Period of Juguo, and the father of Juzhiquqiu was feudal; In the eighth year of Gaozu of the Han Dynasty (199 BC), Zhang Shuo, the general of Guquqiu Difeng, was named the Marquis of Anqiu; In the second year of Emperor Jing of the Han Dynasty (148 B.C.), the county was officially named after the Hou State, which belonged to Beihai County, and the seat of governance was on the highlands in the south of the city. At that time, the territory was the land of Anqiu, Chunyu, Chang'an, Wucheng, Zhuxu, Gumu and Pingchang counties, which belonged to two states (Qingzhou, Xuzhou) and three counties (Beihai County, Langya County, and Gaomi County).

Qianqian County: It is located in the southwest of Jiaozhou City, Shandong Province, and belongs to Langya County.

Xiahe City: It is located 23.5 kilometers southwest of Huangdao District, Qingdao City, 6.8 kilometers away from Langya Terrace, and west of the central part of Langya Town.

During the Spring and Autumn Period, Xiahe City was the capital of the Yue Kingdom, and its name was Langya. According to the "Historical Records", there is the ancient city of Langya ten miles northwest of Langyatai. In the late Spring and Autumn period, the Yue Kingdom destroyed Wu, and its territory expanded to the coastal zone south of the Great Wall of Qi. Gou Jian dominated the Central Plains, and once made Langya. "Wu Yue Chunqiu" recorded: "Yue Wang Goujian 25 years of apprenticeship Langya, set up a viewing platform to look at the East China Sea. Then he ordered Qin, Jin, Qi, and Chu to respect the Zhou room and make a blood alliance".

After Gou Jian's death, his descendants were defeated by Chu. The capital was moved to Wu (present-day Suzhou, Jiangsu Province). Langya became a city in Yue.

Qin annihilated the Six Kingdoms, unified the world, and implemented the county system. It is divided into 36 counties, and Langya County is located in Xiahe City.

During the Western Han Dynasty, Han Gaozu was four years old and placed Langya County here. In the seventh year of the Lv Dynasty, the county was changed to the Langya Kingdom, and Liu Ze of the Feng clan was the king of Langya. In the first year of Emperor Xiaowen, the country was abolished and the county was restored. When Wang Dumang was the emperor, he changed his name to fill the county. Later Han County was moved to Dongwu (now Zhucheng), with 51 counties under its jurisdiction, and Langya was relocated to a county. Emperor Wu of the Han Dynasty visited this place twice in the fifth year of Yuanfeng (106 BC) and the third year of Taizhi (94 BC) and visited Langyatai.

During the Eastern Han Dynasty, Langya was still a county and belonged to the country of Langya.
