a trip to shanghai

I went to shanghai to participate a training held in Dec. 26, this training is about how to use an online application ,which was a software used in the field of logistics. time for training was just one day, fortunately the trainer was a pretty young girl, her voice was sweet,and she kept on speaking ,it was a delightful thing to listen to her . I was not familiar with this city because this is my first time being there. our customer is a branch of an U.S. owned company . In shanghai ,people speak english more frequently. I also noticed that some areas were not prosperous ,just as stagnant as the suburban areas in wuhan. like most metropolis ,there are networks of subway , which make traveling within this city very convenient. before came back to wuhan , I went to shanghai arboretum, there was quiet and I really enjoyed staying there , I took several pictures there . during the days I stayed and traveled in shanghai , I felt the people there are very hostipitable, at least better than most people in wuhan .
