After a long time of traveling, I accidentally discovered the yellowed diary of the memorial and opened it.
"He always asks me why I call him Ji Yang. I absolutely can't answer him now."
"Although there were many times when I wanted to tell him what Ji Yang meant, I chose to keep my mouth shut."
"A secret that cannot be told."
"Although I don't say it, I want him to know. I'm afraid that he will know, but I'm also afraid that he won't know."
"I call him Ji Yang because I hope he can like me like Yang Shu. Like him like me."
Concept: The love meaning of the poplar tree is that it will not die for a thousand years, it will not fall down for a thousand years, and it will not decay after a thousand years. To me, the poplar tree represents unwavering love.
