FM Transmitter: Please help decode diagram/power properly (Mandarin or Catonese would be helpful) Answered

I just need to figure out how to power this thing!

Notice the positive marks in both upper corners, the negative in both lower?

The large circle is the microphone, which is fully wired. The smaller circle is the frequency modulation, which is all set as well.

The underside only has holes where the gray squares are and is otherwise clean (exception being one spot where the two mounting prongs of the microphone pushed through.)

Thanks

Okay, confusing development. I got the English diagram. Why would I wire the same circuit twice? Is it possible, just poor design?

You don't wire it twice. it just offers 2 sets of pads to supply power too. So you can have a battery connected to one side or the other. This will probably run on 3V to 5V. So try a couple of AAA batteries and see how it goes.
