The age of Lajia site is about 4000 years ago. According to experts' appraisal and analysis, the areal remains unearthed from Lajia site in Qinghai are noodles made of millet, which is the earliest noodle remains so far.

Lajia Site, located in Lajia Village, guan ting zhen, Minhe County, Qinghai Province, is a large settlement site in Neolithic Age, known as "Pompeii in the East". Lajia site is a prehistoric site, including Miaodigou period, Majiayao culture, Qijia culture, Xindian culture and other types of prehistoric and bronze age ancient cultural sites.

It is understandable to find noodles at Lajia site, which is the birthplace of the Yellow River, the mother river of China. In the upper reaches of the Yellow River, China people invented noodles, which later became the exclusive staple food of the whole Yellow River basin. Because of this development process, it is inevitable that the noodle ruins were first discovered in China.
