> When Mercury or Venus is at inferior conjuction, it is between us and the sun, and it is moving from the evening sky into the morning sky.
> 我看不懂後面"it is moving from the evening sky into the morning sky"在說什麼.
> At superior conjunction, when the plant is on the opposite side of the sun, it is moving back into the evening sky.
> 一樣是看不懂後面"it is moving back into the evening sky"
> 可以麻煩大大們解釋一下嗎?
