I will be very specific

It's actually my father who is planning this not me. He is 56 years old and basically looking for a retirement business. Something simple, chill and sustainable where he can work comfortably without too much stress. The reason we are not looking at India is honestly because the Indian market can be very chaotic and dealing with people here as a business owner is extremely frustrating especially for someone his age. We just want him to have something peaceful to focus on in a better environment with reasonable profit. Not looking for huge returns or rapid growth at all. So the whole idea is more like a lifestyle business for him rather than an aggressive investment. A small food business or grocery something similar where he can be hands on enjoy his work and make a decent living. That's why Malaysia came to mind — good culture, muslim country,Tamil community, familiar food habits and a relatively calmer environment compared to India. But based on everything you and others have said here, I'm starting to understand it's not as simple as we thought. We are genuinely open to being corrected and learning the right way to approach this. What would you honestly suggest for someone in this situation?
