From August 29, 2016 to September 7, 2016, a group of four people, including the general manager of COLIY China and senior R&D personnel of the Chinese company, were invited by Swiss Metrolab and Swiss SENIS to conduct technical seminars in Switzerland. The meeting mainly discussed the advantages and performance of each company's latest products and mutual product complementarity, the technical cooperation of new products in the next stage, the application cases of products in different regions, and how each company in the same industry can use their respective advantages to strengthen market promotion. The meeting was a complete success.
