Grandparents are taiwanese

Hi all . I would seriously need some good advise . I am holding a Singapore passport , just like my parents . My mom used to be a Taiwanese but had given up Taiwan citizenship 30 years ago . My grandparents are all Taiwan citizen .
My question is , am I able to stay in Taiwan or somehow change my citizenship to Taiwan ? , would it help if my grandparents or uncles whom are Taiwanese citizens able to help ?
Thanks in advance

What is the reason for wanting a Taiwanese passport.
Is there any value in having it.
Can you have dual citizenship which is required before you can get the passport. 
It may take years to get the citizenship so you can then get a passport.

Best you check out the Taiwan Govt immigration website to see if you can get the correct information.

thanks , you're right . but i still need to know . am in Taiwan now with my mom . i ll do some checking .....

Singapore doesn't allow dual nationality. I think having a Singaporean passport is pretty cool, but you know Taiwan is an amazing place.
