I remember one time when he visited Hong Kong, I walked him back to Robert Black College at HKU after the dinner. We stopped in front of Run Run Shaw Building, and Prof. Lai had a long chat with me about research and career. We just stood there and talked until nearly 2am, and he shared lots of inspiring experience and suggestions; I still find them so useful as of today.

I have kept thinking of Prof. Lai from time to time since his departure, especially all the things that he affected me. He was so nice and caring, especially for the next generation, and I myself am certainly one of those who benefit from his guidance.

Thank you, Prof. Lai, and we shall miss you for long.
