No matter what kind of advertisement you want to do,
you need the flyer (and 16-page brochure, and video).
It is better to ask Chuan Lin to design for you right now,
and latter, you may use it or may not use it.
If you want to use it, you have to print it (flyer). In our experience,
you may have to print the flyer 10 times of your tickets.
For example, you have 3,000 tickets to sell, then you may have
to print 30,000 flyer to distribute to potential audiences.
