The Malaysian world No 4 pair lost 21-14, 22-24, 14-21 to their 11th ranked rivals in a match that lasted 72 minutes.
After winning the first game, Pearly-Thinaah were on the brink of winning the tie when they had match points twice in the second game.
However, Yi Fan-Shu Xian made a comeback and forced a rubber game, which saw a point-for-point exchange before the Chinese pair won the match.
Pearly-Thinaah have met the Chinese shuttlers four times so far in their career and lost on three occasions.
In the all-Malaysian men’s doubles quarter-final, Asian champions Aaron Chia-Soh Wooi Yik avenged their defeat to Man Wei Chong-Tee Kai Wun at the Malaysia Masters final last week by winning in straight games in Singapore.
The world No 3 duo took just 33 minutes to tame their 7th ranked compatriots 22-20, 21-17 to set up a semi-final clash with India’s Chirag Shetty-Satwiksairaj Rankireddy.
Earlier, Malaysian fans were left disappointed when men’s doubles top seeds Goh Sze Fei-Nur Izzuddin Rumsani were sent packing by Shetty-Rankireddy in straight games.
Mixed doubles pair Goh Soon Huat-Shevon Jemie Lai and men’s singles player Leong Jun Hao were also bundled out in the quarter-finals.
