aloha Cheryl-Anne,
Marie likes 4 because that is the number that is connected with “Small Wood” (Nine Directions Chart).
There are a lot of different thoughts regarding bamboo stalks in other feng shui systems, cultural beliefs, as well as a bunch of retailers retailers looking for a way to sell more bamboo.
Your best bet is to decide on what system you are going to participate in and do so.
Best,
Shawn
