Building a Factory in a Distant Location

He Ning had mixed feelings when he found out that Qiao Mei had built a factory and purposely chose to do it in the western suburbs, which was very far away from him. The eastern suburbs where he lived now clearly had the most land. The land was also cheaper and closer to Qiao Mei's house than the western suburbs, but Qiao Mei still chose to go to the other side.

It would make sense if Qiao Mei was in the business of planting crops like fruits. The land in the eastern suburbs was not suitable for growing crops, and even the fruit trees sold in the nurseries were transported from the western suburbs. However, Qiao Mei did not have any special requirements for the land, so why did she not choose the cheaper land?
