My conclusion is that it is impossible for Chinese people to travel without arranging a plentiful supply of snack foods, regardless of whether they are going in a car, on a train, or an airplane. Any Chinese people that I know are almost continuously nibbling on snack foods as they travel along.
I like almost any kind of salted crackers but I don't like those salted preserved plums. I tried them one time. Yahhhh!! All I can remember was that the water I drank immediately afterwards was the sweetest water I''ve ever tasted!
What is your favourite snack food for travelling?
