Leaving chopsticks in rice
Leaving chopsticks standing upright in rice is avoided in Japan and China because it looks like incense or an offering set out for the dead. Laid across the bowl or on a rest, they signal only a pause in the meal.
What it may mean
The trouble with upright chopsticks is what they resemble. A rice bowl with two sticks standing in it looks like the bowl set out for the dead, with incense rising from it, and so an ordinary meal suddenly looks like an offering. Japanese households, an encyclopedia from 1903 notes, saw it as foretelling a death; a student from a Shandong family called it a very popular belief that he follows because it makes people uncomfortable. The fix is simple: when you pause, lay the sticks across the bowl or on a rest. That small motion says something about pauses in general, since how you set a thing down halfway matters. A task left standing upright, half done and in plain view, can unsettle a room in the same way.
Depending on how you saw it
A child doing it at dinner
Children often learn this rule by being told "not like that" before anyone explains why, sometimes with a quick hand moving the sticks flat. Which rule did you learn that way, long before you knew the reason?
Abroad, at a restaurant
Travelers often break the rule without knowing it and notice only when a server discreetly lays the sticks down. Most hosts forgive a guest at once. What do you do when you realize you have broken a rule you did not know existed?
Kept as manners, not belief
Many people who never think about spirits still avoid upright chopsticks and feel uneasy when others do it, keeping the gesture as plain table manners. Which of your habits has outlived the belief that started it?
Why it happens in nature
In funeral and ancestor rites in China and Japan, rice is set out for the dead, and sticks of incense stand upright in offering bowls, so chopsticks planted in rice resemble that offering. Today the rule is also everyday table etiquette, followed by many who hold no belief about it.

China (Shandong)
A student whose family is from Tsingtao (Qingdao), Shandong, said you cannot stick your chopsticks into the rice in your bowl, because they look like incense burned for the dead, which makes the rice food for dead people.

When you pause in the middle of something, where and how do you set it down?
