Am i able to enter hongkong with chinese visa?

Hi, Chinese visa only allows you to enter mainland China, and you cannot use it to go to HK. You should apply for a entry permit for HK in advance. First, you should prepare the relevant documents: travel itinerary, copy of passport, the application form, 2 passport-style photos, introduction letter from sponsor and the sponsor's HK address and the TEL, working certificate, financial support proof, flight tickets. Next, submit the application to China embassy in your home country.
