General Xing and both refer to the stars in geomantic omen, but their functions and properties are different. General refers to the star that assists the main star, and is usually used to resolve some minor evils, such as five ghosts and three evils. Chen Yuan refers to the main star, which plays a more important role and can affect people's fate and fortune. According to Feng Shui theory, Chen Yuan's influence can't be resolved. He can only adjust his fortune by changing his environment and his own way. Therefore, the average star can't resolve Chen Yuan and can only adjust his fortune through other methods.
