The shape of the small sanxian is special, and it is different from other ethnic groups. The exquisite and graceful body is made of a whole piece of pear wood or tea wood. Legend has it that there was only one string at first, and it gradually increased to three strings. The sound of the piano is lingering, like Wan Lai in a quiet night, the moon shines on the empty forest, a little dark thoughts suddenly arise in the evening, the clear sound gradually becomes urgent, and gradually soaks into the night after a short noise, and there are a few overtones, and the wind leaves, The sound of the stream and the roar of insects are mixed together. The name of the song is "Ma Li Hua Kai", the Ma Li in Lahu language is pear blossom, the music is like a little pear flower fragrance in the heavenly palace, and the bright white light scatters into the cottage of the Lahu people, like the Qingming season, the moonlight melts, Infiltrated on the white pear blossoms in the mountains, which are covered with water vapor and without a bit of dust. Lahu people love pear flowers, their white color, and their sweet fruit.
