Nickname for Leung Chun-ying (梁振英 Liáng Zhènyīng), who became the Chief Executive and President of the Executive Council of Hong Kong in 2012. There is speculation that Leung is a closeted member of the Chinese Communist Party.
Secretary is a high position in the Chinese Communist Party. For example, the mayor of a Chinese city is also that city’s municipal Communist Party Committee secretary.
Congratulations, Secretary Leung. I hope you won’t forget to pay your party fees!
Congratulations, Hong Kong, on officially joining the Celestial Empire. Secretary Leung will start rolling in the cash now.
