I could be wrong ... prob got it right though...
Red and black are usualy DC colours even in China, the bat is 9v so put black to neg(bat) just touch pos ... just a glance... if it is wrong... it is AC 0>20 V any way so should be able to handle a flash of 9VDC...
The blue and yellow are AC ... it could get confusing here, I am going to stop.
Blue is usualy neg ...
