In the early days of Lake Moho, only natural rain and flood could be stored. In the Tang Dynasty, Chengdu's urban water conservancy developed in an all-round way. In the first year of Zhenyuan in Tang Dezong (785), Wei Gaokai Yuxi was connected with Maha Pool. In the seventh year of Emperor Xuanzong of the Tang Dynasty (853), Jinshui River (Forbidden River) was opened in Bai Min, which drained from the west to the city, merged into Maha Pool, connected with Yuxi, and merged into Youzi River (Fuhe River) to the east. According to Li Yuan's Shu Shui Jing in the Qing Dynasty, Liu Jiang "flows into the county seat of Chengdu in the east as Jinshui River, into Mohe Pool in the east, into Yuxi in the east, out of Huayang County in the east and into Youzi River". Thus, a complete river and lake system of urban water conservancy facilities in Chengdu has been constructed, which has injected sufficient water and vitality into the Maha Pool. In the 11th year of Xian Tong, Tang Yizong (870), Nanzhao invaded Sichuan, and refugees poured into Chengdu. When Chengdu was short of water, the refugees took mud juice from Maha Pond to drink.
For thousands of years, the Maha Pool has been a place to play. It was famous for a time, and many literati and poets came here to play. By the middle of the Tang Dynasty, it had become a famous scenic spot in Chengdu, and both literati and ordinary people loved to visit it. Gao Pian, a famous poet in the Tang Dynasty, described the "intoxicating" of the Moho Pool as "underestimating Ge, the willow color is as new, and intoxicated the youth on the Moho Pool", and Du Fu, a poet sage, "Don't frighten the egrets, but keep Qingxi as a companion". The beauty of the Maha Pool made Lu You "ecstatic" in the Song Dynasty.
At the excavation site, there are two cobblestone paths near the Maha Pool. During the Southern Song Dynasty, pebbles were yellow and stones were arranged radially. The cobblestones in the Tang Dynasty were blue-gray and arranged in parallel. "This is the path along the shore of the Maha Pool," said Yi Li. Although there is a "greenway" beside the pond to prove its former glory, since the Tang Dynasty, the area of the pond began to shrink, and among the "slag building" of the backfill pond cleaned on site, there were those from the Tang Dynasty.
When we arrived in Shu, the Maha Pool was no longer a place where everyone could play. In the 5th year of Yongping (AD 9 15), when Wang Jian, the former Shu emperor, built a new palace, he merged the Mahachi into the palace and renamed it Long yuechi county. After Wang Yan succeeded to the throne, he expanded the palace, injected flowing water into Long yuechi county, renamed Xuanhua Pool, and built palaces, pavilions and pavilions around the pool, covering an area of ten miles. Mrs. Hua Tuo, the wife of Meng Changjun, the master of Shu, described it as "just like the beautiful scenery in the south of the Yangtze River" and "Penglai in Shui Xin" in Gong Ci.
From the Five Dynasties to the Song Dynasty, the water source of the Mahachi gradually dried up. In the 18th year of Hongwu in Ming Dynasty, Chunzhu, the king of Shu, filled up most of the Maha Pool and built the Shu Palace on the former site of Houshu Palace. At the excavation site, you can also see a "stepping road" in the late Ming Dynasty. After crossing this 2-meter-wide blue brick road, you can take a boat by the pool.
In the late Ming and early Qing dynasties, Shu was destroyed by war. In the fourth year of Emperor Kangxi of Qing Dynasty (1665), a tribute court was built on the site of Shu, and there was still a little water in the northwest corner. It was not until the third year of the Republic of China (19 14) that it was completely filled as a martial arts field. At this point, it lasted 1300 years, which made Wu, a poet in the Tang Dynasty, and Lu You, a poet in the Southern Song Dynasty, look forward to flowers every day. "Mahatai Chi Yuan" disappeared without a trace, leaving endless regrets and yearning for future generations. If it were still here today, it would be no less than the West Lake.
According to historical records such as Biography of the King of Shu, Records of Huayang and Records of Shu, Li Bing, the Shu Shou of the State of Qin, ordered five stone rhinos to be carved when Dujiangyan was built, two of which were transported to Chengdu, and the other three were in the guanxian River, which served as the town water stone gods. So some people think that this is a water control beast created by Li Bing. In the Tang Dynasty, the original exhibition hall of Tianfu Square was surrounded by a 500-acre lake called Mahachi. It is said that this water beast was discovered by 1973, but no one dared to move.
