There are nine geographical bisectors in the top view. Which nine are they? Can you draw it for me? Tu Tu Yao Tu Tu map

I have never heard of the concept of nine diagrams. I helped you find the top view of the summer solstice in the northern hemisphere (below), including three pictures: figure 1, figure 2 and figure 3.

Theoretically, the bisection should be 3×4= 12, but the top views of the vernal equinox and the autumnal equinox are actually the same, so the second bisection will be combined into one.

Speaking of which, you should be able to draw the remaining six by yourself _
