Dr Ding is a conscientious scientist in China. China needs more such scientists serving the nation.
Ms Chai is a journalist whose brain is washed and loses a basic conscientiousness as an indepedentant interlectual. Too bad! Many people similar to her in China need to work and live upon themselves in western countries for at least 5 years, and then would understand why Dr Ding has such passion to discuss or address the questions from Ms Chai.
