To work in Macao, it is necessary to know Cantonese first. Besides, you'd better know some English. The agent recommended that there is a reliable employment center behind Gongbei Lvdu Hotel, which specially transports workers to Macau. And more formal. The cost seems to depend on the conditions. The ordinary introduction fee may be about 3000 yuan, and all the procedures have to be done by yourself. A friend of mine used to go to Macau from there.
Well, I didn't ask carefully at that time. You'd better find out for yourself!
