Zhenbei Terrace is located on the top of the red hill in the north of Yulin City. The town of Taibei was an observation post on the Great Wall during the Ming Dynasty. It historically was also the place where the Mongolian and Han people would negotiate. Due to the threat faced, it controls the throat of the south and the north like a giant key and became one of the most important fortresses along the ancient Great Wall. Standing on the high Zhenbei Terrace, watching the scenery from the top, there is almost a feeling of actually being at an ancient time in history.
