"The Legislative Council is the law-making body of the Hong Kong Special Administrative Region. It comprises 70 members, with 35 elected directly by geographical constituencies and 35 elected by functional, occupation-based constituencies. Apart from its law-making function, the Legislative Council debates issues of public interest, examines and approves budgets, receives and debates the Chief Executive's policy addresses, and endorses the appointment and removal of the judges of the Court of Final Appeal and the Chief Judge of the High Court."
So their legislature is 50% industry experts. The Executive Council can be made up of experts as well, but it doesn't have to be.
Take education as an example. The Secretary for Education is a businessman, however there is an educator in the legislature, the Voluntary Chief Executive (Development), Hong Kong Professional Teachers' Union.
