周公解梦 is a Chinese-language website offering a free dream-interpretation lookup service based on traditional dream dictionaries and related reference materials. The site says its content is compiled from published Chinese dream-interpretation texts and Western psychology books, and emphasizes that interpretations are for entertainment rather than a basis for superstition or important decisions. Visitors can browse explanations by subject, including people, animals, plants, objects, activities, everyday experiences, and natural events, or record dreams and use an online platform for answers.

Beyond dream interpretation, the site provides a broad collection of cultural and lifestyle tools. These include Chinese zodiac, horoscope and blood-type information; lunar and solar calendar conversion; fortune and birth-chart readings; name scoring, matching, and naming services for babies, adults, companies, and shops; and guides to physiognomy, palmistry, and related traditions. Its extensive searchable topic catalog covers many common dream images and scenarios, from family members and animals to travel, work, relationships, illness, and weather
