Hi,didn't you know there was contrudiction in Jinbi's conjecture.He wrote"美国CIA,FBI的经验,技术和水平,会查不出他杀么?'但因为他是医生,很容易做到自我了断,而找不出死因来的'.According his logic, CIA,FBI的经验,技术和水平are useless for doctors.I only want to say Li did not commit suicide as he had road to go.So,my idea is sense.I think Mao was a great man but had a lot of mistakes.
