Yan's return is a good thing, a clever swallow. There are magpies reporting good news among the people, and Qiao Yan returns. This is a good thing. Take care of them!
Old people say this is a good thing. It is said that swallows nest in places with good feng shui. If there is a swallow's nest, that place has good feng shui. Swallow itself is a lucky bird.
If in doubt, please ask.
