Here's a guide on Feng Shui:

But if you don't want to read the whole thing, here are just a few notes on it:
- Having proper Feng Shui increases overall luck in the game, like with Money Rocks or finding rare bugs/fish/items.
- Yellow items = Luck with finding money
- Green items = Luck with the overall game
- Red items = Luck with finding items
- Almost all items with an overall color of either yellow, red, or green count towards your Feng Shui-ness, even clothing or shoes. But Bugs and Fish don't.
Hope this helps
