Love is actually like a well we encounter on the journey of life. We think the water in it can quench our thirst for a lifetime, so we all jump in without hesitation. However, we find that the water dries up soon, so we keep struggling inside and crawling out, but we can never climb out.
We are all digging such a well for ourselves, this is our fate, just like Cheng Dieyi in "Farewell My Concubine", why did Yu Ji die? Cheng Dieyi couldn't find the answer, so he could only "live without going crazy".
