What do you mean, take a name?

Ru (rú) literally means "eat", which means eating. This word was quite common in ancient times. For example, "eating hair and drinking blood" refers to a fierce and cruel beast that feeds on blood and hair. In modern Chinese, the usage of "Ru" is relatively rare, but there are still many words and idioms, such as "Su Ru" and "Being at a loss, eating like fur and drinking like blood".

Rú sê refers to vegetarian food that does not eat animal products such as meat, and usually refers to followers of Buddhism or Taoism. Rosin is regarded as a healthy eating habit, because plant food is healthier and more nutritious than animal food, which is beneficial to human health. Rusu can also save resources and protect the environment, which conforms to the healthy, environmentally friendly and low-carbon lifestyle of modern people.

Eating animals like fur is an old saying, which means that some wild animals or fierce animals are so cruel that they even want to eat blood and fur. Being at a loss means that a person is in a very difficult situation and doesn't know what to do. Although these two idioms seem to have little connection, they both describe animals at first, and then they are extended to people. Eat like animals and drink like blood, describing fierce fighting and being at a loss, describing confusion and trouble.
