Finally, I have watched the full lectures. Many thanks to Prof. Hong Liu for the intuitive yet rigorous lectures on the framework of QFT. Maybe, I'll watch the lectures once agian to fully grasp his ideas.

1st lecture: 100, 000 views
last lecture: 2, 500 views 



2.5 people out of 100 actually finished the course and not even that, because 25th lecture has 1, 100 views . It shows how hard it is to have the dedication to finish, but i am sure everyone who watched the entire thing got very rewarded due to the enlightenment they got. So everyone who reds this, please give yourself a pat on the back for what you have gained. And everyone who did not, no problem but remember that you did not gained as much as you could have gained.

Great waiting for Quantum Theory lectures !
Which could've uploaded before this
