"Your Majesty, do you remember the summer that was washed away by the heavy rain?" What do you mean?

This sentence is from Qiong Yao's Princess Pearl: "Your Majesty, do you still remember Xia Yuhe by Daming Lake?" The reason is that I met a woman named Xia when I visited Jinan incognito, and everyone who read this story later knew it. The moral is to ask him if he remembers his old lover.
