Spanish immigrants

First of all, it depends on whether your boyfriend is a Spanish citizen. If your boyfriend doesn't have Spanish nationality and only has a residence permit, it depends on what kind of residence permit, student residence permit or work permit, long-term residence permit or limited residence permit.

According to your boyfriend in Spain, he comes from China and has lived in Spain for two years. Judging from the situation, it can only be called immigration to Spain, not immigration.

Your wedding will be held in China, and your boyfriend should have an unmarried certificate during his stay in Spain. This certificate should be issued by the Embassy or Consulate of China in Spain, with two witnesses. For details, please refer to the website of the Embassy of China in Spain.

After receiving the marriage certificate, the marriage certificate needs to be translated and notarized in English or Spanish as one of the materials for applying for a visa. The specific materials can be found on the website of the Spanish Embassy in China or directly by telephone. After arriving in Spain, apply for a residence permit at the local Aliens Administration or Immigration Bureau.
