Three mice taste wine. The first mouse ate American wine and took three steps before falling down. The second mouse ate Japanese wine, took two steps and fell down.

From the situation analysis, there are five possibilities:

1, if the wine is the same, the mouse who eats Erguotou is the boss, the second one eats American wine, and the third one eats Japanese wine. The eldest drinks a lot, and the third drinks a little;

2. If the three mice drink the same amount of alcohol, then there are: Erguotou has less wine, followed by American wine, and Japanese wine has the most;

3. Japanese wine and American wine are poisonous;

4. The hometown of these three mice is China and they are used to drinking Erguotou;

If three mice drink the same amount of wine, there is another possibility: Erguotou is mixed with water; China's Erguotou contains water-fake wine.

Taken together, these five points mean that three mice are dying.
