I got the 355 sign signed by Zhuge Shen. How can I explain it?

It means that with the help of experts, to find experts, first go to the northeast corner of Chang 'an (capital or bustling metropolis or provincial capital). In other words, if you want to find your goal, you must leave your original place of residence and go to a new city. In the northeast of this city, the corner of Cross Street is the best place for you to find your target. There, at least you can grasp a key clue information. It is not enough to have a geographical location, but also to grasp the time to form effective space-time coordinates. Speaking of Tianmen, it means that there is a summer solstice festival in May, from 1 3 pm.
