"5S Management" containing 5 sets of laws including Structurise, Systematise, Sanitise, Standardize and Self-discipline, is regarded as a prototype for environment and the upgrade of quality and efficiency.

Beginning from the year-end of 1999, Hong Kong Association of 5S inaugurated a "5S Company Certification Plan". Ocean Empire Food Shop was invited to be the first enterprise to participate in and passed the certification successfully. It became the leading food shop in Hong Kong attaining the "5S Management Certificate". The largest reward that the company gained from this certification was to let all staff understand and recognize more about the "5S Management" so as to establish their sense of self-discipline. The culture of "5S Management" has then been deeply rooted in Ocean Empire.

The company in each year would keenly sponsor all offices, workshop section heads and branch supervisors to receive training from the Principal Franchised Assessor of "5S Management", Professor Ho Guang Ming, lead Assessor and Founder Chair of 5S Association, with the purpose to extend this "5S Management" to all these locations.

By setting up an internal "5S Audit Team" and organizing two times as a year the "5S Management Assessment Election", not only the best performed shop and Factory are elected, the actual realization of such management in offices, Factory and branches could be closely monitored
