I'd suggest him switching to Deputy Chief of Bureau or Policy Assistant....
=> Are these 4 master degrees / 1 doctor degree obtained before or after he/she joined the AO? I know one civil servant and he has plenty of time for study and he has already obtained 4 master degrees at the age of 36.
=> The 1st part is questionable and the 2nd part is bullshxt. A lot of organizations can offer over HKD100K for experienced executives. Given his brilliant CV, I don't think it is impossible.
