Video quoted from

That method of work,
in my country,
did it that way a few decades ago,
When I went to the factory to check the tiles,
I have also seen it.
The process of that method is very laborious work.
Because there are a lot of manual programs,
But now no factory is willing to do that,
Because the tiles are cheap and the wages are rising very high,
So that method of work,
In my country, now no one has adopted it.
Very helpless !
