I really hope they will survive, but I think a lot of their kids no longer want to continue their parents legacy.
Most likely the kids moved to the city and work here. We have two wet markets around here and, of course, the pasar malam every Saturday night, but I really miss Sarawak exotic fruits and vegetables. There's a Borneo market in Serdang that is open almost every Saturday morning (I think), but it's quite far from my place.
