What materials do I need to prepare for a visa on arrival when I travel to Indonesia with a China passport? thank you

Just: 1. My passport. Round trip air ticket 3. The disembarkation card filled in on the plane contains your personal information, where you will stay during your stay in Jakarta, the expected length of stay and other information. This card is filled in English. If you don't understand English, you can ask the flight attendant for help. This card is given to the immigration office, and there is a stub behind the airport window. When you leave the country, you need to give it to the immigration office again.
