If you have signed a six month, one year or two year…contract can you leave under Taiwan law with one month notice regardless of contract.?Lets say there is no specific reason , but you just don’t like it ? A person writes “This job is too stressful for me right now so here is one month notice”
I don’t want to get into the morality or ethics of the subject , just the legal side. 
I don’t know about the legal side, but ultimately no one can force you to continue doing a job you don’t want to do. In this situation (which I’ve been in, albeit not in Taiwan), I’d just speak to the employer politely and honestly, tell them you want to leave but will give them time to find a replacement, and see how they react. It’s not really beneficial for the employer to have an employee who doesn’t want to be there, either.
That is very good advice, and politeness goes a long way (in general). 
It can’t hurt to slip in a “sick father” or “grandfather”. It’s a standard “get out of jail card” for many Taiwanese.
We’ve been over the dead relative scam before. 
(Oh, sorry. It’s just a sick relative this time. I suppose that’s better. 
)
Actually, we’ve been over OP’s question before, numerous times. The short answer is no, unless the contract gives you the right to quit on a whim (or as Andrew suggests, you persuade your employer to let you go). Otherwise, you need a valid reason to terminate the contract, which could be under LSA Art. 14 or (if you’re a permanent resident with a permanent job) Art. 15, or Civil Code Art. 489.
We’ve also been over breach penalties numerous times – tldr, for basic jobs they are rarely worth pursuing.
If in doubt, ask a lawyer.
