In the winter of Beijing, the silver is wrapped up, the flowers and trees are dying, and the bitter cold is hard to find a trace of life. However, in Changping, a suburb of Beijing, the strawberries growing in the greenhouse are like a ruby ​​ruby, attracting countless tourists to watch the harvest. "The wind is cold outside the house, the strawberry in the shed is fragrant; the red strawberry is delicate and tender, and the picking is smiling." This is the true portrayal of the Changping strawberry picking season. Changping strawberry grows in the mountain front warm belt at the foot of Yanshan Mountain. The unique climatic conditions and pure and pollution-free natural environment make it form its own unique flavor and taste. Changping strawberry fruit is full, with fresh bracts; fruit is bright red, bright color; fruit shape is neat, beautiful and uniform; flesh is reddish, meat is fine; juice is sweet and sweet, rich in aroma, worthy of its "fruit queen" reputation.

Changping is located in the suburbs of the capital, 30 kilometers away from the urban area. The Yanshan Mountains traverse the east and west, forming a natural barrier. The north is bounded by the Yanshan and Nanzhao Jingmi diversion canals, and the middle is a narrow hilly hilly landform from east to west. It is the "warm belt in front of the mountain." At the southern end of the warm zone, the Jingmi diversion channel flows slowly from east to west, separating the mountains and plains organically, such as the same natural “air conditioning” to regulate the regional microclimate. The water that Changping apples drink is taken from the deep layer of water filtered by layer below 200M. From the test results of Beijing Municipal Center for Disease Control and Prevention, we can see that the water contains zinc, strontium, selenium, metasilicate and so on. Beneficial minerals, pure water quality, basically reach the standard of silicon-based natural drinking mineral water. The quality of Changping apples grown with mineral water is naturally different.
