The story of "Sending Goose Feathers A Thousand Miles Away" happened in the Tang Dynasty. At that time, in order to express his support for the Tang Dynasty, the leader of a minority group in Yunnan sent a special envoy, Mian Bogao, to donate swans to Taizong. When passing by the Mianyang River, the kind-hearted Mian Bogao released the swan from the cage and wanted to give it a bath. Unexpectedly, the swan spread its wings and flew high into the sky. Uncle Mian hurriedly reached out to catch it, but only managed to pull out a few goose feathers. Uncle Mian was so anxious that he stamped his feet, beat his chest, and howled loudly. The followers advised him: "It has flown away, and there is no point crying. It is better to think of a remedy." After thinking about it, Mian Bogao could only do this. When he arrived in Chang'an, Mian Bogao met with Emperor Taizong of the Tang Dynasty and presented him with gifts. When Emperor Taizong of the Tang Dynasty saw that it was an exquisite satin bag, he asked someone to open it and found a few goose feathers and a small poem. The poem says: "Swans pay tribute to the Tang Dynasty. The mountains are high and the road is far away. The treasure is lost in the Mianyang River and falls to the ground crying. The Holy Emperor can spare Burmese Bogao. The courtesy is light but the affection is heavy. Send goose feathers thousands of miles away." Taizong of the Tang Dynasty was inexplicable. Burmese Bo Gao immediately told the whole story.
Emperor Taizong of the Tang Dynasty said repeatedly: "It's so precious! It's so precious! Sending goose feathers from thousands of miles away is a small gift but a big deal of affection!"
