unfortunately this one only can buy through agent. Actually better can do online. I think after certain age, you need to do health screening and self declare if you have pre-existing.
And don't try to false declare if you have pre-existing. They can dig your health record from the all hospital and lab here when you claim big sum. I repeat, don't ever try.
I see real case my colleague kena reject because he claim the insurance for some surgery less than a year after he subscribe. I cannot remember because he have HBP or pre-diabetes.
