The first moring after the national's day,I met a woman pushing a baby carriage and bringing a big suitcases in the metro.she was going downstairs,but there was no elevator ,I saw a foreigner man was helping her lifting the front wheels of the baby carriage and she has to hold the back side of it ,she was meant but failed to drag her suitcase downstairs,I thought the man must be her husband,but after he went away I knew he just helped her too,then we got on the same train she was so thankfull and said I was the first chinese helped her in china ,I don't know how to explain to her .I said most chinese are helpfull maybe they're just not so brave to step forward to help a foreigner ,then she said she had traveled here for a week and was getting back to spain ,I find many foreigners here in china would feel frustrated or upset with the behavior of somebody or when they need to do sth.What should we do to change this situation instead of leaving a disappoint impression after they get back I was wondering whether there is or should we found an volenteer orginazition to provide free help for foreigners?so that we can promote understanding and friendship between nations.
