Prior work has documented the effectiveness of traditional heating methods for building in improving indoor air
quality and reducing high-level pollution exposure. In recent years, a majority of researchers has Proposed views
which improving indoor heating equipment, for example, Zhang[14,15] reports that solar Chinese kang and burningcave
in a new heating methods improved indoor thermal environment. EzzatiMbinda [4]introduced comparison of
emissions and residential exposure from traditional and improved cook stoves in Kenya. However, these studies
have either been short-term studies or have not focused on indoor pollution transport path. In this study we tested the
indoor particulate matter PM2.5 pollution transport path for typical rural building. What we tested and surveyed
from all cases indicated that rural indoor environment need to improved
