I grew up in Nanyou, and I usually like to make some handicrafts. When I was in high school, I often went to the cultural square in Chikan to decorate classrooms and my home wholesale. There are such small bags as you mentioned, and they are very cheap. There are all kinds of soft yarns, colored balloons and wedding invitations. They are all wholesale. Even if you don't buy it wholesale, retail is cheaper than buying it in Nanyou! Many stationery stores and boutiques in Nanyou buy goods there. You can transition from Nanyou to Xiashan, and you can take a bus when you get out of the dock. You can take bus No.2 to "Cunjin Bus Station", and get off and you can see Aihua Square. There is an old street next to it, where stationery is wholesale. I hope I can help you. Everyone is from Nanyou, and they are very friendly. I wish you a happy wedding, happiness and a hundred years of harmony.
