1. Skin color: Indians are generally dark, Xinjiang people are relatively white, and Pakistanis may be in the middle tone.
2. Facial features: Indians may have thick eyebrows, big eyes, prominent nose and full cheekbones. Because Pakistanis have been influenced by the intersection of civilizations in Central Asia, the Middle East, Persia and India for a long time, their facial features may be more similar to those in the Middle East or Europe, while Xinjiang people have distinct facial features.
3. Taste: Both Indians and Pakistanis like to eat curry, but since most people in Pakistan are Muslims, they will consciously pay attention to hygiene and change it frequently. In contrast, India's concept of health may be slightly weaker.
However, these characteristics are not absolute. Everyone is unique and may be influenced by mixed genes. Therefore, for accurate identification, more complicated methods, such as gene detection, may be needed. At the same time, we should respect everyone's uniqueness and avoid generalizing the whole group with a single feature.
