The triangular pattern on the satchel has no special meaning in geomantic omen and will not have any influence on geomantic omen. Feng Shui is a science about the relationship between man and nature, which holds that the relationship between man and nature can affect one's life fortune.
So, if you like the triangular pattern on the bag, you can use it with confidence. However, it should be noted that Feng Shui is not a science and cannot be used as the only basis for decision-making.
