As the function is singing, and the contexts are lyric, the nostalgia ci which belongs to the Tang and Five-Dynasties has three features: first, it didn't borrow all of the ancient poems' three types, just adopted two of them, ignored the discussion type.

Therefore, the nostalgia ci in Tang and Five-Dynasties is full of desolate and lost atmosphere.
