Thank you very much for answer my query. However, I am still unsure of some concepts. Quote: Robert Lee wrote: It simply means that the two ba zi chart's pillar clashes. In this case, the two heavenly stem of the day clashes with each other. What is signified by a clash? Quarrels? Difficulties? Quote: So based on this factor, it shows a not so compatible chart. However, as long as the horoscope signs do not clash as well, then there are still ways to improve the harmony. Such as having more Water element as a common binding element to improve the harmony between the two. As water will exhaust the excess metal and make weak wood stronger. Can two people with not so compatible chart get along? I am dog, while he is goat. Is there still ways to improve the harmony? Thanks in advance for your help.
