Suggestions for Kuala Lumpur trip.

As the title says, this April I am going for a 3-4 days trip to KL, can you guys suggest something unique there. I went through so many vlogs but found those things boring, like all those things such as cool building shopping centres I can find them here in delhi ncr too. I am looking for something like cultural places or tours there where I can learn and know about the locals and their culture more , by this I mean not the city dwellers but actually locals. I want to experience their culture, nature etc.
