They used plates instead of bowls, in which case bowls were reserved only for soup.
Some used chopsticks coupled with a Chinese porcelain spoon, whereas others adopted the combination of spoon and folk.
A large, common spoon is prepared for every dish, to transfer food to one's own plate so that the individual's chopsticks or spoons never touch the "public" food. I was at first very impressed...
I mean, by the perseverance to insist on such troublesome and distancing table etiquette.
