Beijing recalling its big guns to handle a more complex city
It needs more experts to help it deal with the political, economic and diplomatic issues

Last week, while a 29-year-old American stole the limelight in Hong Kong and the world, a Beijing veteran on Hong Kong's political and legal affairs quietly went back to the capital from Macau.
The two men have nothing in common and the events are not connected. The timing was just a coincidence, but there are some interesting messages that can be drawn from the events.
Edward Snowden, the former CIA technical assistant, sought refuge in Hong Kong after exposing the United States National Security Agency's massive covert surveillance programme called Prism.
He chose the city because he had no reason to doubt Hong Kong's legal system, he told the South China Morning Post in an exclusive interview last week.
He earlier said "… Hong Kong has a reputation for freedom in spite of the People's Republic of China".
While the city buzzed with Snowden's revelations, 58-year-old Xu Ze, the former deputy director of the central government's liaison office in Macau, was transferred back to Beijing to the Hong Kong and Macau Affairs Office under the State Council which he left nine years ago.
