That is very cool. Are there really that many burials where you are? I've never seen a coffin for sale in my time here, and assumed that unless you're in the countryside pretty much everyone is cremated. My wife's family had to pay a hefty bribe to be able to bury her grandfather (on ancestral land) rather than have him cremated, but I hadn't thought to ask about the coffin.
I have no idea how many burials happen here. Riding around over the years I've often seen graves, or those pointy headstone things that mark a site. They appear in odd spots, like on small hills beside roads. Presumably they were there before the roads became roads. But I've never seen any big ole cemetery, nor even enough burial sites to justify a coffin industry. The dudes who seem to make the coffins have tiny shops beside this one road, maybe two or three coffins on display, maybe room at the back for a few more. Perhaps they have grandma in there and aren't coffin-makers at all. It's a small street in a large village/suburb-like area well outside the city center, but it gets a lot of traffic passing through and counts as the main street for the local area. In another five to ten years it'll have been overrun by all the suburban development that's going on out there, but, say, ten or fifteen years ago it would have been fairly isolated. I dunno. I just notice the coffins every time I ride past.
