Now, Qingdao Metro has come into our life.The first line of Qingdao Metro was opened on December 16th 2015.Until December 2017, the length of Qingdao Metro reached fifty kilometers andcovered four districts. Qingdao Metro not only reduces the traffic jams butalso benefits our lives and the economy. When it is built, I will volunteer to keepthe order in the Metro and help the old to get on and off the train. I hope QingdaoMetro can make our city more beautiful and more convenient.
