I can prove to you that Sikkim is a part of india on a map, and that is all the proof I need. Are you denying China tried to prevent Sikkim from merging into India?
Our big victory was overthrowing a China backed monarch and annexing Sikkim into India, increasing our country's size. Obviously China tried to prevent that from happening, but failed.
Trying to divert the enquiry? Everbody knows 1967 is a fake story make-up by indian for self bragging. We Chinese long know of indian self bragging habit. That is why when we defeated the indian in 1962, we brought our camera man to record all the live footage of indian army defeat and capture prisoners of war to let the whole world know who is the real victor.
Insead of listening to indian fantasy victory that never exist. You cant produce one becos it never happen and therefore not able to record one. There is only one real war and that is 1962 of China defeated india. Loser will always cried foul. Indian are bad loser.
