Qijiaju has a long history. According to records, in the Ming Dynasty, in order to seize the throne, Zhu Di, the king of Yan, launched a four-year tug-of-war with government troops in Hebei, Shandong, Henan and Anhui. It was known as the "Battle of Jingnan" in history and popularly known as "The King of Yan's Sweep to the North". The people of the Central Plains, who had gone through wars and famines and longed to live and work in peace and contentment, had deep-rooted ideas of foolish loyalty and spontaneously helped the government troops resist the Yan army. King Yan's army suffered repeated setbacks, which made King Yan furious. So every time he attacked a place, he massacred the city, stripped the land, and massacred the people inhumanely, making the area south of Yanjing "six hundred to seven hundred miles from east to west, and nearly a thousand miles from north to south." "It's almost like a ruin." However, in this tragic scene, perhaps because of God's kindness, one village was spared. It turned out that when the Yan army was approaching, a heavy fog suddenly fell and enveloped the village. The villagers were glad to have passed by, so they changed the name of the village to "Qi Jia Wu", which later became known as "Qi Jia Wu". This is the origin of today's Qijiaju. Therefore, it has become one of the oldest villages in the North China Plain. Naturally, it has created Qijiaju's long historical and cultural heritage and continued the ancient and simple good folk customs. In this ancient and blessed land full of historical accumulation, the ancient Yellow River flowed here for more than 300 years; Dayu once controlled the water here and dredged up the nine rivers; Duke Huan of Qi paid homage to his generals to protect the border, and Emperor Wu of the Han Dynasty visited the sea eastward. Ancient anecdotes such as Emperor Xizong of the Tang Dynasty worshiping Magu God and Mu Guiying removing her armor are also sung here. The most fascinating thing is the winter jujube culture here. In Juguan Village, Qijiajia Township, there is an ancient jujube forest with an area of ??1,000 acres. This is the only oldest original winter jujube forest found in the world so far. There are 1,067 ancient jujube trees in the forest, including ancient ones that are more than 600 years old. There are 198 trees. According to the Liu family tree record, in the second year of Yongle in the Ming Dynasty (AD 1404), Hong Gong, the founder of the Liu family who moved to Cang, led his four sons and two nephews and their families to immigrate northward from Jimo County, Shandong Province, and traveled to the northeast of Cangzhou. He was unbearably hungry and thirsty. I saw a jujube forest. The jujubes were as big as apples. Everyone ate them. They were crispy in the mouth, sweet and delicious, and they felt refreshed. They thought they were immortal jujubes given by the gods, so they established a village here and named it "Gathering Hall". During the Zhengtong period of the Ming Dynasty (1436-1450 AD), Wang Ao, the official of the Ministry of Civil Affairs, returned to his hometown from Beijing. On the way, he ate Juguan winter jujube and praised it as "indescribably beautiful". When he returned to his hometown of Wangmaoquan (now Haixing County, 40 kilometers away from Juguan), he ordered the villagers to plant winter jujube trees to enjoy the delicacies of the world. Later, it was gradually introduced to Shandong and other places. Empress Zhang of Xiaozong of the Ming Dynasty, the first wife of Emperor Hongzhi (AD 1470-1505), was a native of Xingji, Cang County. In the third year of Hongzhi's reign, in order to control floods, Empress Zhang ordered her younger brothers Zhang Heling and Zhang Yanling to supervise the dredging of the Jiahe River, which was known as the "Empress River" at the time. "Niangniang River" crosses Qijiaju, passing through Qianfu, Longzhuang, Juguan, Taoyuan and other villages, with a total length of 96 kilometers. When the uncles of the two countries supervised the excavation of the Xingjijia River, they found winter jujubes in Juguan, so they had them picked and presented to the emperor and queen. The winter jujubes were favored by the palace as soon as they entered the palace, and were called "the best of jujubes" and "the best of all fruits" by Emperor Hongzhi. "King", he was immediately designated as a "tribute" and came to the court every year. This system was followed until the Qing Dynasty, and winter dates became "tribute dates". There are countless beautiful folk legends about winter jujube, forming a unique winter jujube culture. Today, Juguan’s original winter jujube forest is not only listed as a national key cultural relic protection unit as a precious historical and cultural heritage, but also has become a well-known eco-tourism site. Every year, a large number of tourists wander here, explore historical monuments, and listen to Beautiful legends, taste the Dongzao culture, immerse yourself in it, and please your soul.
