Obituary for Wu-Cheng Tsai

Wu-Cheng Tsai, 93, a longtime resident of Westford, passed away peacefully on Monday, January 22, 2024 at Lowell General Hospital surrounded by his loving family. He was the beloved husband of Chuen Ing (Liaw) Tsai with whom he shared 52 years of marriage.

Wu-Cheng was born in the city of Tainan, Taiwan on September 20, 1930, to the late Hi Yaung and Jin (Wu) Tsai, the second son of seven brothers and sisters. During World War II, his family would seek refuge in the countryside to escape the bombing.

Shortly after the defeat of the Nationalist Chinese Kuomintang forces on the Chinese Mainland, he was conscripted into national service for two years. Awarded with a scholarship, he left post-war Taiwan in the 1950s, to study at Tohoku University in Sendai, Japan with a degree in electrical engineering and concentration in semiconductors. Eventually he was forced to flee Taiwan as the Kuomintang sponsored White Terror killed or imprisoned Taiwanese civilians and political dissidents. He later immigrated to the United States on a student visa to attend Washington University in St. Louis, MO. Wu-Cheng met his wife Chuen-Ing Liaw in New York City, NY in 1971. The Tsai family relocated to Westford, MA in 1981 where he worked as an engineer with numerous technology companies designing modems and printers, as well as worked in the defense industry on guidance systems. Being multilingual and fluent in Japanese, Mandarin Chinese, Taiwanese and English he spent much of his time traveling for work.

Wu-Cheng was also a very active person who enjoyed running, playing tennis, and swimming. He could be seen jogging along the streets of Westford in his very distinctive pink jogging pants. In his later years, he was a long-time member at the former Westford Racquet and Fitness Club where he would swim daily. Wu-Cheng also had a passion for amateur photography, classical music and karaoke and would often sing in the shower, to the dismay of his family. Post retirement, he and his wife spent several years traveling around the world and visited every continent except Africa. He even managed to set foot in both the Arctic and Antarctica in his late 80s. In his last remaining years, as Parkinson’s took away his freedom, he undertook it without complaint and with a grace and dignity that exemplified his character and the love he had for his family.

In addition to his loving wife, Wu-Cheng leaved his two sons, Yau-Liong Tsai and his wife Catherine of Nashua, NH, and Pin-Bo Tsai and his wife Angelique Eliopoulos, and grandchildren, Penelope and Miko of Chelmsford, MA.

Funeral services and interment will be held privately.
