Jensen K. Feng, 72, who was active in the Chinese-Christian Church of Greater Washington in Silver Spring, died Friday of cardio-respiratory arrest at The Mount Vernon Hospital in Alexandria.

Before moving to this country in 1969, Mr. Feng, a native of Hankow, China, had been in government service in China and Taiwan and had been assigned to the Chinese mission in Tokyo after World War II. He retired in 1953.

Active in church affairs throughout his lifetime, he helped establish the first Chinese-Christian church in Okinawa while teaching at the university there.

After moving to this area, he worked briefly for Woodward/Lothrop and for a brief time operated a corner grocery store in Washington.

Mr. Feng then devoted full time to Chinese-Christian Church, where he served as a vice chairman of the board of directors.

A student of the Bible, he taught Sunday School and Bible classes to Cantonese-speaking church members. In 1976, he returned to Taiwan where he spent a year teaching the Bible to inmates of Taiwan prisons on a church-sponsored mission. He returned here last November because of ill health.

Survivors include his wife, Tsai-ying Lee, and a daughter, Janet Tsou, both of the home in McLean; three sons, David, of Dearborn, Mich., George, of Wheaton, and Jerry, of Falls Church, two brothers and six sisters and one grandchild.

The family suggests that expressions of sympathy be in the form of contributions to the Book Fund, c/o the Chinese-Christian Church of Greater Washington, Silver Spring.
