After my father and mother passed away, I would only occasionally use trips to Japan for conferences or teaching to also visit my brothers and sisters. A few years ago, I also accepted an invitation from the National Science Council to lecture at Hsinchu's National Tsing Hua University.
父母親過世後，只有偶然利用到日本參加會議或教學，才順道和兄弟姊妹聚一下，幾年前也曾應國科會邀請到新竹清華大學講學。
