i am maid working in Singapore. I was plan going for holiday to beijing on my own. how to get visa?

You can apply for it at the CVASC office in Singapore. First, prepare all necessary documents, such as your passport, a photocopy of the passport, a fully completed application form attached with your bare-headed color photo, the original and photocopy of your residence permit in Singapore, and round-trip tickets and hotel bookings. You may also need to provide a financial standing proof. After you submit all the documents, wait for about four working days and the result will come out. Then go to the office to get your passport back.
