Here's some further reading for you on this topic: https://www.marxists.org/reference/archive/strong-anna-louise/1959/tibet/index.htm
It's a book written by an American journalist who visited Tibet just as it was in the process of abolishing serfdom, and got to witness it in person and talk to the people there who told their stories about what life was like before.
Highly, highly recommend every communist to read this at least once.
