I have been hearing a lot of good feedback about the seminar conducted by Pak Hen. Some even attended all his seminars. I told myself that I'm not going to miss this seminar again.
A have attended few seminars. Some are very basic and you can read from book. Some are trying to promote their products instead of tell you the secret of swiftlet farming. If you really what to learn from true "sifu", make sure you make yourself available for this seminar.
