If you have a GP you trust, go there first to get a diagnosis. Then ask for a referral. If you don't have one you trust, you might still try to get a referral and then ask the specialist what sort of procedure they use.
Mesh is fairly widely used in hernia repair these days, so I'd be surprised if Zhongxiao were the only hospital using it. The procedure of choice probably varies, but they're probably using a tension-free repair, where they cover the abdominal wall defect with mesh. The other common approach would be to sew the defect together; sometimes the wound is closed with sutures and reinforced with mesh, I think. Some centers use laparoscopy, but usually only in select situations as it's more expensive. You might want to look up some treatment guidelines for hernia repair so go for your visit well armed. This Medscape article provides a lot of background information, although you will probably need to register to view it:

Also ask about the rate of recurrent hernias at the hospital--rates vary, but it should probably be <10%.
FWIW, heres an abstract of an article from surgeons at Cathay General:
