If you are used to dance folk dance, then there are many choices. Let's start with the lesser used ones ---- feather fans and group fans (mostly used for classical dance).
But I think what you are referring to is definitely not the above. It's probably the normal kind used for fan dancing.
This kind of words, or use the bamboo sheet as the fan bone is good, with plastic, a get it wrong, will be like a group of aunts in the square dance ......
So when it comes to the bamboo sheet as the fan bone of the fan, the main look at the three sorts of things:
Bamboo ---- (the quality of which I guess you won't be able to look at, so just pick the thorns a little less right);
Fabric --- (cheap, there are mainly two kinds, one is a hook into a mass of lines of the kind of fabric similar to the cheapest red flag of the kind, a look and the former almost the same, but the quality of a slightly better ...... of course, the quality of the poor it does not matter, you can buy back to their own processing of a little bit of it, I buy the cheapest every time, and then come back with a paste or glue. Back with paste or glue to strengthen the fan bone and fan adhesion, and then use a fire engine to gently burn the open fan extension, so that after burning, the fan is not easy to be drawn, of course, to be careful ...... not to burn off.)
Size ----- (This is the most important! You can also say the length, the length of the fan bone, and the radius of the fan) I made a point of turning mine over and measuring it. I have three kinds, one of them is our own customized, one of them is a normal one, I think you should use this one --- the fan bone is 30 cm long, plus a long floating out fan surface a **** 40 inside. There is another kind is the fan of the cloth lengthened, I think you do not fit, so do not expand on it.
Lastly, I suggest you buy on Taobao ...... very cheap. A few dollars a handful only
