Qijia Culture is a late Neolithic culture centered on Gansu Province, China. It has entered the stage of copper-stone blending. Its name comes from the Qijiaping site in Guanghe County, Gansu Province. Qijiaping site 1924  was discovered by archaeologist Anteson.
Qijia culture, which spans about 2200 BC to 1600 BC, is an archaeological culture of special value in the upper reaches of the Yellow River. It mainly distributes in the eastern part of Gansu Province, which is nearly 1000 kilometers west to Zhangye and east to west of Qinghai Lake. It spans Gansu, Ningxia, Qinghai, Inner Mongolia and other four provinces. With the deepening of the study of Qijia culture, Qijia culture has become one of the important research objects to explore the formation and early development of Chinese civilization, and its influence at home and abroad is expanding day by day. 
Qijia culture is about 4000 years old. ]
There are Yubi (meat is better than good), Yuhuan (meat is better than good), Yuying (better than meat), Lianbi, Lianbi (commonly known as Sanhebi), Duojuan Lianbi, Heteromorphic Bi (such as Sanya Bi, Yuxuanbi's original shape) and so on. Shanju can also be considered as a part of Bi, which evolved from Bi. Most of the materials used are local or near materials (which are mainly subject to the economic and traffic conditions at that time), including a small amount of Hetian jade, and some suspected Qinghai jade. As far as its material is concerned, there are stone (most common, not discussed here), semi-stone, semi-jade, jade, turquoise, Tianhe stone, shells (not discussed here). Most of the jade materials used are of good texture, including white, cyan-white, topaz, sugar, jasper, ink, gray, etc., as well as variegated jades between different colors. Modern archaeological excavation and jade mining prove that there are abundant jade deposits in the area of Qijia culture. According to the author's observation, the most material used in Qijia culture is Mayan Mountain, which is located at the junction of Yuzhong County and Lintao County. The quality of jade is relatively good and close to Hetian Jade. There are also jade from Wushan, Jishishan, Qilian Mountain and other places, occasionally suspected of Qinghai Jade. Of course, the quality of Hetian jade is better and more rare.
In ancient times, there has been the saying that "beautiful jade unearthed from the west" and that "the Eastern soil is inferior to the middle soil, and the middle soil is inferior to the western soil" in modern antique circles. I think the main points here are two aspects: one is that the material quality of jade produced in Western China is better; the other is that the natural conditions such as drought, less rain and loess landform in Western China make the environmental conditions of jade burial relatively good, which is more conducive to the preservation of jade.
