I don't know when it started
Mahjong mattresses gradually faded out of public view
It became a "childhood memory"
A mahjong mattress with "meat".
A bamboo mat with a mark on your face when you fall asleep
There are always straw mats with "barbs".
……
It is being "ice silk mat" "latex mat"
These new products are replaced
How to choose between new fabrics and "old traditions"?
