Is Beihang University near here?

I'm not sure where Hongliyuan Hotel is. If you can take a bus at Liuliqiao Beili, I can tell you that the 103 express train goes directly to Beihang University.

If you go to Zhongguancun, there are 323 buses in Li Nan and Liuliqiao Beili to Zhongguancun Street, or many buses take other buses to Zhongguancun.

Zhongguancun is not far from Beihang University. Wait for bus No.386 836 944 at the east of Xueyuan Bridge. There are cars going to Zhongguancun everywhere ... When you get to Zhongguancun, ask the financial center.
