What does it mean that Duke Zhou dreamed that his father bought tea?

Dreaming of buying tea means:

A lucky day. Confidence has doubled, and the pessimism that has been suppressed in my heart has been completely thrown away. If you haven't tried your work/study, you might as well try it today. This is a good time to tap your talents. The friends of the opposite sex I want to meet today are very controlling and like to advocate for you, but they will also protect you!
