today i went to Haining for one day's trip,almost all the memebers of the unit took part in this collective activities.i used to regard this trip we will go to visist some party historical sites,however,when i arrived the destination i was informed this trip is a pure collective travelling.we spent three  hours  in rambling around the leather city of Haining ,most of us bought something back.in the after noon we runned over the old house of a prime minister of feudal (封建的) china.time passed quickly ,we went back to our own city and had a dinner together.it's the first time to have a trip with other unit members,and i regard this trip is a good experience.enclosed some pictures :
