What are the specific definitions of the annual "projects under development" and "new projects" in the company's annual board of directors' work report, and what is their relationship? Thank you

Bethel: Dear investors: Hello! The number of projects under development refers to the number of projects that are in the process of research and development and have not yet been mass-produced; the number of new projects refers to the number of new designated projects in the year. The order is: obtain new designated projects - transfer to projects under development - transfer to mass-produced projects. Thank you for your attention!
