In feng shui for the bedroom, one of the major taboos would be to position the bed with the headboard sharing the same wall with the stove directly on the other side.
Anyone sleeping on such a bed location will become impatient and short-tempered over time.
Thus, it came to me as a surprise when I watched a documentary about Northern rural China, where it is a norm in certain villages to deliberately position their bed this way. This is because of the cold temperature they experience most part of the year. By having the bed behind the stove, the warmth created after cooking will help to warm their bed before their bedtime. Since they use wood as the fuel, the smouldering can provide warm throughout the night.
Hence, in their environment, this feng shui taboo has lost its significance and instead providede a more conducive living condition. Very interesting.
