Feng Shui master Lai Buyi was a bucket of gold in the Song Dynasty. What does this mean?

This sentence seems to string three different people or things together, without clear context and meaning. Song did not refer to a certain point in the Song Dynasty, nor did Shen Xiang and Jin Dou elaborate. Lai Buyi is a common name, which can refer to a historical figure or a character in a novel. So this sentence has no definite meaning and background at present.
