@JiqunL @ACM_CHIIR Congrats! Will you share a preprint? Curious to read

[Roger Zhe Li @Zhe_Delft]

Thanks to this man who made my English name. So honorable that I saw you play in person in Rotterdam 4 years ago and witnessed your last peak form. No sadness for me, but just congrats on such a career, my GOAT.

This random seed is with me for so many years. It is my duty not to forget.

Good night, Beijing. Good night, those people who did not fall asleep.

Also proud of @adidas and @tudelft. I never regret to be part of you.
