Shandong people belong to the ancient Dongyi nationality, with tall appearance, strong physique and strong desire to conquer. Shandong people are generally taller, which is influenced by many factors. First of all, Shandong is located in North China, with high latitude, low temperature and slow metabolism, which is conducive to height development. Secondly, the dietary habits of Shandong people also have an impact on their height. Shandong people's staple food is pasta and rice, with side dishes. This kind of diet is reasonable in structure and can provide the nutrients needed by the body. In addition, Shandong people eat more calcium-containing things and dairy products, which also contributes to the development of height. Finally, Shandong people have a strong sense of conquest and competition, which also makes them pay more attention to physical health and exercise, thus contributing to the growth of height.
