Chinese Visa Application

Hello,

Good Day! I will be applying for the Chinese Visa next week. I just want to ask if the fastest processing time for it is 2 days? because my Aunt had theirs in the US and they have it on the day they applied for the Visa. I'm just curious if we still have the same processing time here in Manila? One more thing If I already have the Ticket, Hotel Reservation plus my financial docs there is no need for me to have an Invitation Letter right? as long as I have the rest of the docs?Thanks
