Original poem
Song yuting
Qing palace zizhen
Lord of the five mountains, king of the south of the city.
A thousand people shake hands and make my sleeves smell good for three years.
[Translation 1]
Your charm is fascinating and unforgettable.
Remember that meeting in the crowd?
You just shook my hand, but you stained my sleeve with your fragrance.
How many years have passed, and it has never dissipated.
[Translation 2]
In the vast sea of people,
The person I want to see most is how many years you will go through.
I am eagerly looking forward to how many opportunities I have missed.
Among the thousands of people, even if there is only one chance to shake hands,
That's enough. My sleeve will keep your elegance and fragrance.
Will not dissipate for a long time.
