I prefer Traditional Chinese over the Simplified version.

YOU

你 = (Male variant) You → Today many use it a neutral term for all genders spoken to

妳 = (Female variant) You → Used when referring to a female or to the mother nature

您 = (Polite variant) You → more formal for honorable persons, often used when meeting a stranger or a senior/elder/client that you would want to show respect to

祢 = (Religious variant) You → used when spoken to a higher presence, such as a spirit or God

儞/爾/尔 = (Archaic variant) You → singular informal, may find them in books or when people try to speak in a archaic style

儂 = (Informal variant of Wu) You

ME, MYSELF, AND I

吾 = (Archaic, dialectal variant) I, me, my, our

俺 = (Dialectal varaint) I, me, my; we, us, our

阿拉 = (Regional variant of Wu) we, I, me

THIRD PERSON

他 = (Masculine variant) he; him; another → Today many use it a neutral term for all gender/object/being spoken of
