Because your couplets are Buddhist customs and mine are Taoist customs. The two verb-object words "washing hands and burning incense" and "sincerely fasting" are very neat in grammar and content. "Listen" is "he" (hè), both of which are verbs. "Bai Fan" is Buddhist music and Taoism is "chanting", but for the sake of balance, I am right about "chanting".
Limited by my ability, I dare not say perfect, but I want to be neat! I hope it helps you!
