Let your friends also enjoy wealth, Mother said

In a few days time Chinese all over the world will be celebrating the Lunar New Year. One of the customs is to give Manadarin oranges to close friends. I have not been proactively giving Mandarin oranges to friends. However, I always make it a point to return the same if I do receive them. I remember my Mother had told me many times that when a friend give you Mandarin oranges it symbolizes he/she is bringing you wealth. Therefore if you receive, you must give the same in return so that your friend would also enjoy wealth.
