From the legal level, there is no law that stipulates that instant noodles cannot be eaten on high-speed rail, but from the perspective of public morality, instant noodles should not be eaten on high-speed rail.
First of all, the space of high-speed rail is relatively closed, there are many people, the space is small, and the seats are often next to each other and relatively close to each other. In this case, the seasoning and fried dough of instant noodles are brewed at high water temperature, and they emit a strong mixture of strong smells, such as fragrant, spicy, spicy, numb, meaty, fried, and other odors. These scents are pleasant for the brewer, but not necessarily for others, especially those with sensitive feelings, and may cause discomfort.
Secondly, instant noodles are not absolutely undisturbing to others or affecting the public environment. The process of tearing off instant noodles will generate waste (plastic packaging), and when you open the box, some instant noodles may come out, and when you tear open the oil packets and material packets, it is easy to spill the soup on the passengers. If the owner of instant noodles makes the sound of sucking noodles when eating, it will be even more unpleasant. There was once an incident where passengers quarreled over eating instant noodles on the high-speed train, which made the wonderful trip less enjoyable.
High-speed rail is a public place, it belongs to public space, it is completely different from private space. Therefore, for the sake of your own pleasant travel, you should still restrain your behavior, after all, what is convenient with others is ultimately convenient with yourself. You can eat relatively light meals on the high-speed train or bring some easy-to-operate, non-disturbing food (such as bread, biscuits, coffee, mineral water) on the train, and when you get off the train, you can be free in your own private space.
