Sung is of Ningbo, Zhejiang ancestry and was born in Hong Kong.

His father was an optometrist in Shanghai before World War II.

The junior Sung was born in 1959; he went to the Chinese Children Institute for elementary school and entered Queen's College in 1971, finishing in 1976 after Secondary 5.

After his internship at Queen Mary Hospital, spending six months each in medicine and orthopaedic surgery, he received his Bachelor of Medicine, Bachelor of Surgery degree from the University of Hong Kong in 1983.

Before he went to Canada, Sung had joined the newly opened Prince of Wales Hospital in 1984, first as a Registrar in pathology, then as a Medical Officer in the medical department, and then as a Fellow specialising in hepatology and gastroenterology.

He then went to Canada to study microbial ecology in 1989, after being awarded a Croucher Foundation Fellowship.

The 1-year scholarship was extended by six months only, but he was then awarded the Izaak Walton Killam Memorial Scholarship, the most prestigious graduate award in the University of Alberta, to cover the rest of his 3-year stay.

They got married on 1 January 1989.

Both of them are Christians.

Sung's two daughters both pursued medicine.

Sung obtained his PhD from the University of Calgary in 1991 and a Doctor of Medicine from CUHK in 1997.

After his PhD, in 1992, he became a lecturer at the Department of Medicine at CUHK.

Prior to that, Sung was also successively the Associate Dean (Clinical) (2002-2004) and Associate Dean (General Affairs) (2004-2009) of the CUHK Faculty of Medicine, and Head of Shaw College (2008-2010).

During the 2002–2004 SARS outbreak, as the Chairman of the Department of Medicine and Therapeutics, CUHK Faculty of Medicine and Chief of Service at the Department of Medicine and Therapeutics, Prince of Wales Hospital, Sung led the hospital in its response and studied the epidemiology and clinical aspect of the SARS virus, despite not being a respiratory system expert.

The hospital was one of the epicenters, after an infected patient was treated there.

Holding a Croucher Senior Research Fellowship, he went on a 6-month sabbatical in 2004 at Johns Hopkins Bloomberg School of Public Health; he became the Founding Director and Advisor of the CUHK Stanley Ho Centre for Emerging Infectious Diseases upon returning.

As a gastroenterologist, his research spans intestinal bleeding, Helicobacter pylori infection, peptic ulcer, and gastrointestinal cancer.

His team was the first in showing a 1-week course of antibiotic therapy can cure H. pylori infection, treat peptic ulcer and minimize its relapse.

He also pioneered the use of endoscopic procedure in treating ulcer bleeding, reducing the need for surgery.

Sung also chaired the Asia Pacific Working Group on Colorectal Cancer, founded in 2004 with the goal to set up regional guidelines on the prevention and screening for colorectal cancer.

He then was promoted to Chair Professor at the Department of Medicine and Therapeutics and Chief of the Division of Gastroenterology and Hepatology at the same department (until 2006) in 1998, and became the Chairman of the Department of Medicine and Therapeutics next year, until stepping down in 2010 when he assumed the role of President and Vice-Chancellor of CUHK.

Sung was also appointed Mok Hing Yiu Professor of Medicine in 2007.

The first few years Sung's 7-year presidency, which began in 2010, at CUHK oversaw the transition from the English 3-2-2-3 system to the current 3-3-4 system.

The first intake of students for the 5 new colleges, which were founded in 3–4 years prior for this transition, occurred between 2010 and 2012.

As the new university entrance examination, the Hong Kong Diploma of Secondary Education, would debut in 2012, that year would see CUHK beginning its 4-year curriculum and a surge of undergraduate students.

Sung also led the establishment of Chinese University of Hong Kong, Shenzhen in 2014, the planning for the CUHK Medical Centre and the CUHK Strategic Plan 2016–2020.

Sung has also been noted for his response to student activism.

During the 2014 Hong Kong protests, Sung and Peter Mathieson, the then-President and Vice Chancellor of the University of Hong Kong, visited and talked to student protestors, in the hope of calming them down and preventing conflict, not to send any political message.

Towards the end of his vice-chancellorship, he asked the CUHK Student Union to remove pro-independence posters from message boards, and warned the university would remove them if the Student Union refused.

He has edited or authored more than 15 books, including Principles and Practice of Clinical Medicine in Asia (2nd ed.), Gastrointestinal Bleeding (2nd ed.) and Atlas of Clinical Gastrointestinal Endoscopy (3rd ed.).

Sung has penned many chapters in major textbooks as well, including the Oxford Textbook of Medicine (6th ed.), Sleisenger and Fordtran's Gastrointestinal and Liver Disease (8th ed.) and Textbook of Gastroenterology (5th ed.).

Sung and his wife, an obstetrician and gynecologist, were both MBBS students at the University of Hong Kong, and they went to the same hospital for internship training.

Although reappointed for a second term until 2018, he left his presidency early in 2017 and returned to the medical field.

Sung sat on the 2019 Lui Che Woo Prize Welfare Betterment Prize Selection Panel.
