In Chinese pronunciation, there are many sounds similar to "wood". For example, "mother", "wood", "raising" and "dusk" are all different from "alfalfa", so we need to understand its meaning through the context.
The word "alfalfa" is rarely used, but it has appeared in ancient literature. For example, there is a saying in the Book of Songs: "When you are there, you are also in Chu." This sentence means "there are lush vegetation, which also belongs to the category of Chu"
Not only that, but also "alfalfa" is recorded in Historical Records. It is said that in ancient times, in order to prevent the growth of "alfalfa", people burned weeds in the fields in their farming life. This is also an extension of the word "alfalfa", which means "dense weeds"
To sum up, the pinyin of "wood" is rice, which is an ancient Chinese character, literally. Now it is used less frequently in modern Chinese, but it still appears in ancient documents. When reading ancient books and documents, we need to know and master some Chinese characters and words in ancient Chinese. Only in this way can we better understand and appreciate the connotation and value of ancient culture.
