【正确答案】Dear Manager Wang,
I'm the vice president of Peking University. And I'm writing the letter on behalf of the Peking University to introduce my secretary, Zhang Jian, who will be sent to negotiate the internship programme with you.
As is known to us, internships play a significant role. It is a tripartite win-win approach among companies, universities and students. Therefore, we would like to further cement a friendly, long-term relationship with your company to promote students' practical ability. Zhang Jian has been empowered to negotiate with you about this matter and decide on details based on the basis we have achieved last time.
I'm sure a fruitful agreement will be reached, Wish for a successful cooperation.
Peking University
