Chongqing Mei An Sen Technology Co., Ltd. was listed on the Shenzhen Stock Exchange Growth Enterprise Market on November 2, 2011 (GEM code: 300275).

   Mei An Sen is the first listed company in my country to operate coal mine safety monitoring products and systems. Its coal mine safety monitoring system product technology level, coverage rate, and R&D management system rank among the top three in China.

   There are 15,000 coal mines and 130,000 non-coal mines in my country. After the State Administration of Work Safety included the six major coal mine safety systems in the scope of mandatory monitoring management, this year it began to include non-coal mine safety in the national mandatory monitoring management system. This contains huge business opportunities.

   Shenzhen Haoyuan Company and Chongqing Mei Ansen maintain a good cooperative relationship in coal mine safety supervision-fiber optic sensing technology and fiber optic sensing product applications.

   On November 3, Mr. Quan Taifeng, technical director of Mei Ansen, came to Shenzhen Haoyuan Optoelectronics Company for technical exchanges after attending the listing ceremony of the Shenzhen Stock Exchange.
