Hi, I am a Bangladeshi, UAE resident visa holder, I want to visit china with my family and kids.

First, prepare the relevant documents for family S type: your passport and its copy, the application form, a passport-style photo, your residence permit in UAE, an invitation letter from your family, and copies of family member’s passport and residence permit in China, as well as relationship certificate.
Next, submit the application to the embassy of China to apply for the S type for China.

Dear mam/sir,
My family is here in Dubai, living with me. I want to visit china along with my wife and kids in my upcoming vacation. We never travel china before. Please let me know the requirements.
