I am penglin. At first I am quite confident because I thought I have attended the expo for one time. When deciding the title as tremella, we felt concerned. As I am not a local and know little about it and even have no idea about how to investigate. When choosing the members, I select some students in the village. They are very cautious and well- known the tremella. Thanks to mr. wang be with us, the whole process is going smoothly. We takes the tremella as the theme with the aim of let more people know the tremella by collecting, organizing the tongjiang tremella information. This activity is no only a our social practice, but also a way to deepen our computer knowledge.
