On the morning of September 30th, Yang Qingyin sent Luo Ziling several messages about the plan to leave for the trip in the afternoon.
Since it was her first time traveling with Luo Ziling, Yang Qingyin was not very familiar with his habits, so she gave quite a few reminders in her messages.
Luo Ziling, a freshman, had a class gathering in the morning, but was free in the afternoon on the 30th.
He told Yang Qingyin that he had made all the preparations the night before and assured her that she didn't have to worry about anything.
The journey from Yanjing to Datan Town, the location of Jingbei First Prairie, covered about two hundred and eighty-something kilometers and would normally take around five hours, so in order to reach the destination before dark, they needed to set off after lunch.
The departure time Yang Qingyin and Luo Ziling agreed upon was twelve noon.
