Asymmetrical warfare is the type of war that was found in Vietnam and is now found in Afghanistan. Two opponents, one with massive military power the other with minimal. The big gun needs to end it quickly before their population and military get tired of bleeding. The small gun need to keep it going for as long as possible to bleed the big gun and make him quit.
China has all of the guns and Tibet has none. This is as extreme as this type of conflict can get. Tibet is going to have to withstand immense military pressure and civilian horrors. China will be bled for decades. Tibet and China are in for a lot of pain.
