Mainly depends on whether the second, fourth, sixth and seventh words in the next couplet are relative.
The fourth words "shadow" and "lang" are both accented, and the latter should be changed.
The second words "Shen" and "Bo" are both flat in Mandarin, which seems impossible. However, "Bo" belongs to Rusheng in ancient Chinese, and it is ok as a couplet of traditional cultural common sense.
