How about Tianjin Saiwen Industrial Co., Ltd.

Private enterprise, registered in Singapore. Boss Xu Kui, the company is pretty good, located in Tanggu. I know their vice president Gu Zhenggang, and I also know a few people in the business. History of the family: It started by making packaging for Motorola, and later hired a Japanese as a consultant to specialize in business for Japanese companies. Toyota, Panasonic, Stanley, etc. were all its customers. Not bad. If you have any other questions, you can ask me +QQ 79343364
