Let's begin by stating that most of the people working for Monkey Tree have never attended university or been certified to teach. Quite frankly, most of the people working there are nameless, and anonymous, being trafficked on the international marketplace, and since many are willing, then I'm not sure you can even call them people. Next, let's move on to the fact that no teaching is required of anyone; it is babysitting. Furthermore, the owner of this 'operation,' Ricky Sung, also known as "Mr. Lau" is a crime boss, and a pedophile.
He encourages teachers to engage in prostitution, use drugs, and abuse the children. This is a child pornography, prostitution, money laundering, and illegal drug operation, and any negative comment about this place on eslcafe is immediately taken down. Needless to say, most of the 'teachers' are addicted to either cocaine, heroin, and/or methamphetamine. It is truly a sick, and disgusting place to work, and I would not recommend it to anyone.
There is a good reason that they are always advertising for teachers. They are constantly expanding due to their illegal activities rather than any actual substance. I guess that I should also warn that it is extremely common for 'teachers' to disappear in the middle of the night, and quite frankly, some of them probably do not leave Hong Kong, and end up dead. At least three to four 'teachers' disappear each month and many of them are suicides, but I'm not so sure that these 'teachers' actually commit suicide.
Bottom line: do not work there unless you are interested in moonlighting as a prostitute, and need an unreliable protection racket (and don't mind calling a psychopathic pedophile, 'daddy')
