Mr. YIU began his nursing training in 1974 in Queen Mary Hospital (QMH). As a budding nurse, he was enthusiastic in performing his first debut street cardiopulmonary resuscitation near student nurses quarters in Wan Chai. After graduated in 1977, he commenced his working experience in the Central Sterile Supply Department and rewarded him with a sound knowledge in logistics management and nursing administration for his future career development.

He consolidated experiences in Surgical and Medical nursing during 1984-86 before receiving his emergency nursing training organized by the English National Board (United Kingdom) in 1986. After the overseas training and before he was promoted as a Nursing Officer in the Accident & Emergency Department (A&E) in 1990, he contributed lots of input and promulgated emergency nursing not only in A&E but to nurses in the whole hospital.

During 1991-94, Mr. YIU dawned on his career stage as the first Emergency Nurse Specialist in Hospital Authority (HA).

Lacuna in knowledge, he proceeded to be the first nurse in HA to attain the Advanced Cardiac Life Support course (ACLS) certificate.
