The marriage between Emperor Taizong of Tang and Princess Wencheng led to unexpected people-to-people communication when King Songtsan Gampo granted the intermarriage in 641AD for harmony and peace.

With time, some of the holiday practices from the Chinese calendar found their way into the Tibetan calendar. It is from this that Tibetan New Year became a part of the Tibetan calendar.
