Many people in China are familiar with the lyric（歌词） like this，"If one day I die，please bury（埋）me in the spring，in the spring …"It is from a song called In the Spring．On February 2，we heard"Xuriyanggang"sing this song on the stage of 2011Spring Festival Gala．
"Xuriyanggang"is a duo（组合）of two migrant workers（民工）who work in the capital，Beijing．Wang Xu，44，comes from Henan，and Liu Gang，29，is from Heilongjiang．In late 2010after a video of their singing，they became popular online．They sing in a very natural way，straight from the heart．Their favorite song is In the Spring．The song was recognized by people as a portrait（写照）of migrant workers'life．There are about 200million migrant workers in China．People give them a new name-grass root，which means the basic level of society．Although their life is difficult，they are still singing in the spring with dream，hope and courage．
