Comparing "bici" and "duifang"

彼此 (bǐcǐ) and 对方 (duìfāng) are both personal pronouns, and both can be translated as "each other" in English. 对方(duìfāng), however, points to the "opposite" or "other" side. 彼此 (bǐcǐ), however, stresses "between" or "among each other".

彼此 (bǐcǐ) can be used after personal pronouns like 你们, 我们, and 大家. 对方 (duìfāng) cannot be used in this way.
