What is the best orientation for Xiaguan housing in Dali?

Dali has many mountains and Erhai Lake. I think it depends on the place where the sun rises, the surrounding buildings and the layout of the hillside. If it is flat, the place facing the sun is the most energetic. If the place where the sun rises is covered by buildings or hillsides, just face the direction of Erhai Lake, that is, the direction with the back against the hillside.
