Conflicting parenting opinions with in laws

Hi, When it comes to parenting, my in laws are always want to have a say / telling us that we should do this, not that. Because what we do is wrong and always commenting that we, as ‘小孩子-Young kids’ don’t know anything. In laws are very traditional Chinese ppl who always think they are never wrong. Don’t believe that times have changed and new age parenting methods are completely diff now. How mummies and daddies, howwww? 2 more years for our flat to be ready, alr want to move out so badly :(
