To welcome the new year, households will hang 春聯s (spring couplets) on their doors. The season's greetings are written on red pieces of paper because according to tradition, red color spreads good vibes and scare away the bad spirits. (Firecrackers do the same 🥳). There's so many lunar new year traditions and it's different everywhere. Taiwan has a lot of fun because of the diversity of Chinese culture, immigrants across southeast Asia, and even our own traditions; all sorts of traditions are followed around the island.

The couplets often follow the theme of the zodiac year, people come up with new ones all the time. Chinese is full of homonyms, and the character for dragon 龍 has many to play with. (It also flies, breathes fire, and hangs out with the gods🤣). Lunar New Year is the time of year where calligraphy skills come into play, because come on, spirits don't give out good fortune to those with bad penmanship 🤭, right?

Common sayings are 恭喜發財 新年快樂. For your project, shove in 龍年吉祥 語 in Google and you'll find a bunch of sayings for the dragon year

The one I posted has a 謙卑 (humble) inside a dragon. 一飛沖天 translates roughly to "fly straight up to the sky/heavens"
