"蚕食" (cán shí) in Chinese literally means "to eat like a silkworm", but it is often used metaphorically to describe the gradual and steady encroachment or absorption of something, much like how a silkworm slowly consumes mulberry leaves.

As for "蚕食" by 挽月 (Wǎnyuè), without more context, it's difficult to provide specific information about this work. 挽月 could be an author, poet, or artist, but I don't have enough data to confirm their identity or the nature of the work titled "蚕食". If you can provide more details such as the format (e.g., novel, poem, painting), publication date, or any specific themes or content, I may be able to offer more relevant information.
