On the 1st day of the first lunar month, I will pay a New Year call to all families.
斗胆向楼上高手请教，是否将all改为each更好一些？用a New Year call对应each families，即
On the 1st day of the first lunar month, I will pay a New Year call to each families.
或者On the 1st day of the first lunar month, I will visit my relatives and neighbors to send my new year greetings.因为不可能去陌生人那里拜年的。
呵呵，多年翻译经验教会了我很多东西，要虚心。如果对楼上前辈有所冒犯，望谅解！
