wuhan - one of many provinces in china.
China is huge, maybe wuhan is huge too.. - pardon me but im not an a student when it comes to geography lol.
so they're dubbed and branded as wuhan simply because this items are made in wuhan - china.. there's probably hundreds, maybe thousand cymbal smiths in wuhan alone and trying to find the cream from the crop is no simple task. which's why, just go down to your local lion dance/chinese instrument supplier shop and test their bells in stock.
find the pair that u like - if they let u match with other pairs than thats better...
took me around 6 pairs to finally found the pitch and harmonics of the bell that i like... well it comes in a pair so ur partnet must like the sound of the pair also lah. haha
no doubt the big three and other major cymbal manufacturers create awesome and quality controlled sounding bells but this is the cheaper alternative. just like chinas.
hope this helps.
