>Doctoral thesis inspires
Recently, an acknowledgements section from a doctoral thesis has gone viral.
The author reviewed his bumpy, challenging road to reach this point, which touched a large number of netizens.
"I have come a long way and endured a great deal of hardships to present this dissertation before you," the author, Huang Guoping, wrote at the beginning of his thesis for the Chinese Academy of Sciences.
In the thesis, he mentioned he was born in a mountainous area and his mother left home at 12. His father died in a traffic accident when he was 17.
After going from a middle school in a remote mountainous area to Southwest University in Chongqing, and finally pursuing his doctoral degree in the Chinese Academy of Sciences, he said "he couldn't remember how many times he had felt overwhelmed by the burdens of life." "But my belief was simple. I wanted to keep studying, get out of the mountainous area, and prove I haven't lived in vain."
At the end of the acknowledgement, Huang expressed his wishes. "I hope I can keep a young heart after years of fighting, I hope I have the chance to rediscover the world and live up to what I have suffered in my life. And I would feel it was all worthwhile if I could do something to make someone else's life better."
