When in Taiwan, his wife was a lecturer at a technical institute, but she had no opportunity in California to use her expertise. Because of this she had no option but to study for a degree that would help her to stay permanently in the US. By that time computer science had already become less promising than it used to be, so she altered course and began to study ultrasound technology.
在國內時，太太是一所專科學校講師，她的專長在美西沒有發揮餘地，因此不得不念一個對留下來謀生有幫助的學位，當時電腦已經有點不景氣了，於是她改念超音波檢驗。
