Remember, you are in China, half a civil servant, so what the leader said is just a reference.

I think you should.

First of all, thank you for giving you a chance.

Secondly, I think your company has achieved great success in many fields.

Thirdly, we found some technical problems that can't be solved for the time being, or some theoretical imperfections. Remember to talk only about technology, not management.

Finally, speak your mind, show your determination and how to contribute to solving the problem.

Good luck!
