Mid-Autumn Moon-Great Circle; Side by side parallel,

Sad cutting; Break the whole into parts-decompose,

Railway bend-hyperbolic monk-branch

Don't be ashamed to ask-solve it

Chef operation-how many tangent letters are there-function

You expect me to come, and I expect you to come-equality.

A boat, a bamboo cloak, an old man fishing on the cold river-snow-ordinary vertical line.
