Chinese New Year

I know that the Zodiac is related to the Chinese New Year because every year the animal of the year changes, so every person is a different animal (Unless you`re the same one of course). I also know that in China, at Chinese New Year people get money in packets from people and dress up as dragons and dance to get good luck. I hope to learn about how Chinese New Year was created. Although I`ve never actually been to a real celebration.
