Wen 'an County: Wen 'anwa Wen 'anwa is located in the centers of Beijing, Tianjin, Baoding, Cangzhou and Langfang, with an area of 1028 square kilometers. The wide and clear Haihe River surrounds the northern part of the county like a jade belt. In the rainy season, white sails adorn the river, and the willows on both sides of the river can go directly to Tianjin in the downstream and connect with Baiyangdian in the upstream. The eastern part of Wen 'an is low-lying, commonly known as Dongdian, which is one of the eight depressions in Hebei Province. Longtan: In the north of Luding Village in Wen 'an, there is a pond of 300 mu a year. Because of the deep water, the drought year never dried up. Because this pond has a long history, there are many legends circulating. There is a sea eye in the heart of the pool, which communicates with the Dragon Palace in the East China Sea. The Dragon King visits here through the sea eye every year, so it is called "Longtan". There are stories of big fish stuck in the pond and big oxen drinking water by the pond. These legends can be heard in several counties in this area, and the farther they spread, the more magical they become. Because of this magical legend, Feng, the great president of Beiyang Warlords, was deeply impressed. It is said that when Feng returned to Hejian from Beijing, he personally visited Lumachi Reservoir. When he saw the endless surface of the water and the refreshing water, the legendary "Fairy Island" floated in the pool, surrounded by dense Liu Yin and picturesque lotus flowers in shallow water, he wanted to buy it for himself.

At that time, local gentry also went to Beijing to discuss this matter, but later Feng quickly fell, and this matter failed. "Longtan" has a thorough water depth, and the charming scenery of the island, coupled with the willow trees on the island, makes people feel relaxed and happy. There are also lotus flowers blooming in shallow water, which makes people linger. Dawei River Mosque was built in Yongle period of Ming Dynasty (1403) and rebuilt in Qianlong period of Qing Dynasty. The ancient temple has been repaired through the ages, especially after the recent overhaul, and it is magnificent and magnificent. Yingmen Hall has six columns protruding, and the four-sided corner building is the ridge building. The headdress of the spine is made of animal heads such as faucets, and the pattern is gorgeous and exquisite, basically maintaining the architectural style of the Qianlong period.

According to the inscription in the temple, the favorite Uighur concubine's name is Xiang (it is said that she brings her own incense without adding spices), and the palace named her, so people like to call her. When she went out with Qianlong, she appointed a Hui eunuch Cao to personally supervise the construction of the mosque. Emperor Qianlong personally wrote "aboveboard" and made a gold-plated plaque on the blue background and hung it at the main entrance of the main hall. After Cao eunuch settled in the riverside, he was buried in the village after his death, and his tombstone is still preserved in the temple. The afforestation area in Wen 'an County of 10,000 mu forest farm has reached 250,000 mu. In order to make full use of the advantages of abundant forestry resources, an eco-forestry economic demonstration zone will be built in Wei Jie Farm and other places. Relying on the existing trees, we will vigorously develop various economic projects such as tourism, leisure, vacation and sightseeing by means of animal husbandry, wild breeding, special breeding, forest-grass intercropping and forest-medicine intercropping. Now the first phase of the project has been completed, and the second phase is under intense construction.

After the completion of the "Eco-forestry Economic Demonstration Zone", there are eight zones, including pastoral scenery, natural forest breeding, forest hunting, summer vacation, water park, resort, welcome square and life service. Its main functions are: plant viewing, leisure, vacation, summer vacation, recuperation, sightseeing, entertainment, fitness, catering and so on.
