Luo was born in March 1934 in Singapore, with his ancestral home in Anxi County, Fujian, China.

During the Japanese occupation of Singapore, his uncle and the principal of his school were killed in the Sook Ching massacre.

While a 17-year-old student at The Chinese High School, Luo participated in the anti-colonial movement and was jailed by the British government for more than a year.

His proposed solution is a "theory of balance", which seeks to simultaneously protect and restrain both the power of the administrative organ and the rights of citizens.

In 1997 he was elected as Chairman of the Party, and in the following year, as Vice Chairperson of the Chinese People's Political Consultative Conference (CPPCC).
