6: 30 Chen Xiang Mushroom Head. What does he mean by this sentence?

There is nothing wrong with these words. They mean "your uncle's (things or gifts), your grandmother's (things or gifts), your sister's (things or gifts), and your mother's (things or gifts)", but omitting the following "things or gifts" sounds a bit like swearing. This is the so-called "the speaker is unintentional, the listener is intentional."
