Introduction to Lhasa: Lhasa citizens love this river very much. Every weekend or holiday, groups of Lhasa people drive or walk to the banks and valleys of the Lhasa River, set up tents, fish, or play. Water, or take a bath, drink butter tea, eat various delicacies brought from home, and enjoy the bright sunshine and leisurely atmosphere of Lhasa, much like a Han Chinese picnic.
