There are some factors that rationalize superstition and myth.
First of all, superstition plays a great role. Bailuyuan got its name because there is a legend of white deer here.
It means good luck, Fu Rui. He found a strange plant in Luzilin's field. He asked his brother-in-law, finally surprised.
It is strange to find that this plant is like a white deer. If you grow up in your own home, you will definitely bring yourself good luck.
Secondly, Bai Jiaxuan's psychological reasons. Bai Jiaxuan's previous marriages were unsuccessful, and there was an anecdote about him in the original book. He thought
This is my bad luck or my bad feng shui, which further contributed to Bai Jiaxuan's land exchange.
Finally, it is clearly mentioned in the novel that Bai Jiaxuan used the lack of money and the relocation of his ancestral grave as an excuse to conceal that his land exchange was only for the auspicious feeling in the field. Besides, he also has a piece of land with a font size, which won't have any influence on him. He just has a try mentality. Simple land exchange has become a turning point in the rise of the Bai Jiaxuan family.
