In the development model of employee career, we will clearly plan the career development channel of employees, clarify the positions and responsibilities of employees, and encourage them to make efforts for contribution. For the appointment of managers, we adopt the balanced selection principle of moral character, professional ability and leadership ability. The career development path of employees includes longitudinal rank promotion and horizontal cross-channel development. Longitudinal development mainly refers to the promotion path of internal functions, which develops along the management channel, technical channel or professional channel to enhance personal professional ability. Horizontal development means that while possessing certain professional skills, the technical channels and discipline channels can be promoted to management channels. We will provide more platforms and opportunities for employees to be promoted and developed through longitudinal and horizontal development.
