With the help of Woo's son, P.S. Woo, who joined the business in 1961, Kailey began to further diversify its operations. In 1972, it changed its name to Kailey Enterprises Limited, later forming the Kailey Group, comprising of Kailey Enterprises Ltd; also listed on the Hong Kong Stock Exchange in the same year were Keyble Co, Ltd, Kailey Associates, Kailey Curtis (pte) Ltd, Singapore, and Kailey Senduruan Bhd, Malaysia. Kailey Group's subsidiaries were responsible for property and real estate, investments, supplying plastic, hardware and distributing hair fashion products and equipment respectively.

Born in 1929, Sir Woo Po Shing has largely been responsible for spearheading the Kailey Group. Married in 1956 to Helen Fong Shuet Fun (Lady Helen Woo), they have four sons and a daughter. An education at Hong Kong’s La Salle College and King’s College, University of London in which he obtained an LLB, stood Woo in good stead to establish his own law firm Woo & Kwan in 1963, later known as Woo Kwan Lee & Lo. A successful entrepreneur, Woo has played an active role in many private and public organizations, promoting the arts, advancing the good of the community, and pioneering many social causes. Such activities include the Hong Kong tuberculosis Chest and Heart Disease Association, the Woo Po Shing Gallery of Chinese Bronze Shanghai Museum, Woo Po Shing Overseas Summer School Travelling scholarships and the Po Shing Woo's charitable fund, to name but a few.

Leveraging on its business expertise and industry knowledge, the Kailey Group continued to strive ahead in the 80s, maturing with a vigorous Asian economic climate and setting a tough benchmark for many of its competitors.

After the Group's privatization in 1990, Kailey has increasingly taken advantage of the growing business opportunities in the PRC. Its many China businesses include property development projects in Guangzhou, Qingdao and Shanghai, involving hotels, offices, service and residential apartments for commercial, retail, cultural and recreational use.

Today, Kailey operations comprises of businesses in almost every commercial sector and has proved to be one of Hong Kong most successful family enterprises.

Through generation to generation, Kailey has gone from strength to strength. Today, the Group is run by P.S Woo's son, Dawson, and daughter, Carmen. As it enters into a new millennium, the pair are determined Kailey will remain one of Hong Kong's premier business bastions. With a strong foothold in its accomplished past, the Group will forge ahead. Sustaining its premier position and ever vigilant of new opportunities, Kailey will soar to great heights of success.
