Because China Customs stipulates that China citizens must have a legal foreign visa to leave the country, they are not allowed to leave the country without a visa.
So before you leave China, you must apply for a visa in China.
The visa procedure for going to Indonesia is:
Submit a visa application to embassies and consulates in China. Visa applications can be authorized or entrusted to others. Fill in the visa application form and attach:
Identity information of the applicant; Hold a passport/travel permit valid for at least 6 months; Letter of recommendation from the guarantor or guaranteed living expenses for use in Indonesia if necessary; Round-trip air tickets or air tickets to other countries; Copy of passport; Two recent color photos of 4x6cm (the same size as the passport photo); Receipt of paid visa fee. Submit the applicant's materials and their attachments to the personnel at the visa office window. After the applicant's materials are approved, the applicant will receive a receipt for the visa fee. Payment can be made through China Bank or directly by swiping your card at the window. There is a 0.008% handling fee for credit card payment. After payment, the window staff will return the applicant's materials and the receipt or credit card receipt stamped by the bank staff to the applicant, and then carry out the administrative work of applying for a visa. Visa application needs the approval of the immigration Commissioner, so it needs to be submitted to the immigration Commissioner during the application process;
For example:
Applicants who do not hold a travel permit and a limited stay visa issued by any country and hold a China passport issued by the Ministry of Foreign Affairs of People's Republic of China (PRC) need a letter/instruction from the Ministry of Foreign Affairs of People's Republic of China (PRC).
If you go to Indonesia from other countries, you can apply for landing visa at Indonesian Customs.
