From January 26 to January 29, 2019, we were invited to participate in the 2019 Frankfurt International Paper Products and Office Supplies World Exhibition. The Frankfurt exhibition, held in Frankfurt, Germany, is one of the largest exhibitions in the world which was lasted four days. Our products have been displayed under the attention of  the peers, and we also feel that they value independent research and innovation achievements, as well as their admiration for companies with autonomous intellectual property rights. During the exhibition, we also learned about the customs and cultures of different countries, got the latest international trends, and gained the recognition and respect of European and American customers which made a perfect ending of this trip to Germany.
