Hong Transit Visa

Dear Sir,
I am from Ghana and a PhD Student in China with a valid resident permit from now, till I graduate in 2018 december, I have come to Thailand for 5 days holiday and I transited through Hong Kong for 4 hours, on my way to Thailand. When am returning back to China, I will transit in Hong Kong for 8 hours, I will like to visit the city center and other great places in Hong Kong during my 8 hours transit period before I return back to my campus in China.

Currently am in Thailand and today is my day two here in Thailand. Please I need a transit visa to enable me visit beautiful Hong Kong for just five hours before I take my Hong Kong airways flight back to China.
I have my
Passport,
Passport size picture of my face,
but I do not have my Bank of China financial statement with me here in Thailand.

Can I still apply for the Hong Kong transit entry permit without it or what other alternative can i use to apply apart from my financial statement?

Thank you very much for you support and assistance.
