Generally speaking, when you buy a chair, you pay the bill. From the perspective of geomantic omen, the odd number of chairs is auspicious. Although we often talk about yes-men, it's not even about the number of chairs. On the contrary, the feng shui of even chairs is not so good, which is why people choose odd chairs when buying them. If you want good feng shui at home, you'd better choose a single number when choosing the number of chairs.
