On the second floor, standing on the balcony, there are two cigarettes about one meter apart on the roof of the third floor opposite, and the chimney is about one meter high. Is this feng shui good?

For chimneys, it has nothing to do with feng shui, but it is bad for chimneys. It's about the wind direction. China has a monsoon climate, with northwest wind blowing in winter and southeast wind blowing in summer, so chimneys and windows can't be in the same vertical direction, that is to say, chimneys and windows can't be arranged vertically on the straight line between north and south, nor can they be in the vertical direction of southeast and northwest. No matter spring, summer, autumn and winter, no matter what monsoon will blow smoke into their home.
