Tangerine is an element in many Chinese New Year decoration painting. Because Chinese characters can have many different characters in the same pronunciation or homonyms. 桔 (ju) with the 木 is the fruit, without the wood is 吉(ji)，and 吉 means lucky.
大吉大利（da ji da li）
大吉大利 （da ji da li) "Good Luck & Big Money"
people put money in the red envelope and use it to decorate the tangerine tree is a expression of "good luck and big money"
When you see this character, it also means good luck. People combined 大吉 together and put it this way. My personal opinion is people do that to make it look good in a diamond shape.
If you want a mini Tangerine tree to bring you good luck, you can find that in our mascot section.
