My 15 months old keep touching things, even after I have smack her palm and telling her no. She will just move on and touch other things.. Or if I carried her away, she will just go limp and arch her back. It's getting on my nerve because I'm the only one who will go and stop her. My mil is the one who cares for her during the day. And now I'm resenting her because she allows my Daughter to run around and touch things.. My fil also said, "whatever she wants just let her take." We have told them many times already not to but they just don't listen.. And I'm really frustrated, especially during CNY visiting. My Daughter just go around touching things like nobody's business and what does my in law do? Nothing!

Between 12-36 months old, that's when our LOs start becoming curious about everything in life - the environment, the things, and even their bodies etc. They start with biting things because that's how they start to explore things and understand whether something is safe or not - generally they know that anything that hurts them or doesn't taste good is bad for them! When going to the toddlerhood, they start using their senses - which includes touch! So, it's actually very normal and part of their learning and development to be curious in everything and touching them everywhere :) I'd say that you should just keep the more dangerous things away from her, and give her a firm "no" when she reaches for them - other things, it's okay for her to explore and no real need to be scolding them about it!
