President Xi Jinping encouraged a herding family in the Tibet autonomous region to put down roots in the border area, safeguard Chinese territory and develop their hometown.

Xi, also general secretary of the Central Committee of the Communist Party of China and chairman of the Central Military Commission, made the remarks in a reply delivered on Saturday to Zhoigar and Yangzom - two Tibetan sisters in the township of Yumai in Lhunze county, which sits at the southern foot of the Himalayas.

The two sisters wrote a letter to Xi during the 19th National Congress of the CPC, which ended last week, to report their experiences in safeguarding the country's territory and introducing development and changes in their town, while pledging to make continuous efforts to protect the border. Among their activities is keeping an eye out along the border and reporting suspicious activities like possible smugglers.
