Okay kiddo, let me explain Chinese Indonesian surnames to you.
Firstly, a surname is the last name or family name that a person has. In Chinese culture, surnames come first and are followed by the given name.
Now, Chinese Indonesians are people of Chinese descent who live in Indonesia. They have two types of surnames - the original Chinese surname and an Indonesian surname that was allocated to them by the Indonesian government in 1961.
The reason for this is because Indonesia wanted to assimilate Chinese Indonesians into Indonesian culture and make them feel more like citizens. So, many Chinese Indonesians chose to add an Indonesian surname to their original Chinese surname, creating a double surname.
For example, let's say a person's original Chinese surname was Tan and the Indonesian government allocated them the surname Surya. So now, their full name would be Tan Surya.
It's important to note that not all Chinese Indonesians have an Indonesian surname - some have only their original Chinese surname.
I hope that helps you understand Chinese Indonesian surnames better!
