Visit HK during the break between old and new job.

Hi.
I am holding Myanmar passport and currently working in Singapore. I have resigned my current job and before I start working at my new company, I would like to visit HK for 5 days.My new company has applied EP for me and which is already approved. I understand that I need a company document to apply HK visa. Since I will not be working for both company during that period, I won't have any company letter. Then , how can I apply ?

Hope to hear reply soon.
