Introduction to Laojun's Furrow: "The plow is more dangerous than the building, and the building is dangerous and the plow is sudden." This describes a dangerous ditch-like path sandwiched between steep stone walls. It is unfathomable and has 750 stone steps. Multiple levels. Legend has it that Taishang Laojun saw that there was no way to pass here, so he brought in green oxen and plowed the ravine overnight. To this day, there are still stone ditches on the cliff on the west side that look like plow grooves. It is currently the only way in and out of Laojun Mountain Scenic Area.
