QST prepares and issues the "Sustainability Report" every year. In order to make the major issues concerned and implemented by QST more in line with the needs of stakeholders and to provide a good communication channel between QST and stakeholders, this area is specially set up for stakeholders to provide valuable comments and suggestions at any time, so as to help QST understand your issues of concern and serve as a key reference for corporate governance and information disclosure.

Thank you for your support and assistance.
