Are places such as Shang and Xia Chayu really controlled by India?

Most of the vast territory in the south and southwest of Shangchayu Town is currently illegally occupied by India. Xiachayu Town is located in the southeast corner of Tibet and in the south of Chayu County. It is one of the border towns of Chayu County. It is adjacent to Zhuwagen Town in the east, Shangchayu Town in the northwest, Myanmar in the southeast, and India in the southwest. The border is divided into two sections: China-India and China-Myanmar (the China-India border is 95 kilometers long, and the China-Myanmar border is 25 kilometers long).
