Fun facts. Which players do you remember starting from qualification round, and finally win the tournament? Those achievements are so great in my eyes. I remember quickly Sony Kunchoro some years ago. And from 2019 Kean Yew Loh. For fresh members I could mention they are Ms players.
Zhang Nan and Zhao Yunlei, All England 2010. Beat #1, #2, #4, and #8 seeds after going through qualifiers
