I can't give a definite answer about the cost of Joe Chu of Yang Gongfeng Water Institute (a non-governmental organization in Guilin) because I don't know their specific situation. In China, fees for folk Feng Shui colleges and masters vary from region to region. In some places, feng shui masters will demand high fees, while in others, the fees are relatively low. The same is true for Joe Chu and his college, which depends on the service content and charging standard they provide. If you are interested in their services, you'd better consult their charges directly so as to make your own decision.
