To my dear friend and colleague, thank you for the insights, experience, and humour you brought to every conversation are irreplaceable. It was truly a privilege attending numerous work symposiums with you — I learnt so much by your side, not just about the work we do, but about the importance of camaraderie and genuine passion. Beyond the professional realm, your commitment to our badminton group brought us endless hours of laughter and joy. You weren’t just a valued colleague — you were the heart of our games, always uplifting the team with your spirit. You are solemnly missed, my favourite badminton partner. Thank you for the memories, the lessons, and the laughter.
