But Yang's reaction/non-reaction is strange:

He is key to the whole thing, the question for him is simple:

1. The books have recerived an award, you are one of the contributor on the certificate, so have you received the award?

2. Have you received half of the money associated with the award as Deng has claimed.

If Yes, case closed, Fand is wrong.

If No, case also closed, Deng is guillty.

But he just keeps silent. This seems not right
