Why is the phrase "buy things" in Chinese maidongxi(buy east and west), but not mainanbei(buy south and north)?

There are many theories about this. One theory says it has something to do with Chinese wuxing(五行), the five elements: jin(metal), mu(wood), shui(water), huo(fire)and tu(earth). In Chinese culture, directions were connected to these elements. Usually, east matches gold, west matches wood, south matches water and north matches fire.

In one old story, Zhu Xi, a famous Song Dynasty scholar(学者), met a friend named Sheng Wenhe one day.

"Where are you going?" Zhu asked.

"I'm going to maidongxi(buy something)," Sheng replied, with a basket in his hand.

"Why not mainanbei?" Zhu asked.

"Well, my basket is made of bamboo," Sheng said. "If I say I'm carrying nan(south) and bei(north), it means to put water and fire in my basket. That's not even possible. But if I put dong(east) and xi(west) inside, well, of course my basket can carry metal and wood!"
