Under the majestic Himalayas and in the precipitous Yarlung Zangbo Valley, there is a group of people who guard the lights of thousands of homes with their flaming youth and stabilize the frontiers thousands of miles away with their proud pride. They are soldiers guarding the border and the door gods of the country. They hold steel guns and climb snow-capped mountains and cross river valleys. They guard the great rivers and mountains of the motherland in unknown places and protect the people's happy life.
