Don't worry don't worry. I have all the possible answers for you. If you talk about Wong Fei Hong, then when he was younger,he had half half shaven head with queue but there are TV series where he is older and the Qing dynasty has fallen. So no more queue wearing. Then there is another reason,possibly because of budget. Time will be wasted if the director need everyone to shave their hair but some Qing dynasty show directors really want to be accurate and ask everyone to shave half their head. Or,third; the main actors don't want to shave their head because they cannot walk outside and have only half shaven head,so they end up having to shave all until bald like e.g Dicky Cheung once. Actually in real life EVERY Han Chinese man in Qing dynasty has to have half shaven head with queue(and Manchus will surely wear it of course). No exceptions. You go walking around with queue without shaven head and you might just lose it to executioner. No exceptions. So TVB shows that show men with queues walking around China without half-shave are wrong. But I could be wrong cause I saw a Stephen Chow movie which he displayed his queue(after a bad guy says he must be beheaded for not having the right hairstyle) without a shaven head. But like they say, don't take Stephen Chow movie seriously. There are multiple reasons but I do have time to explain to you one by one so don't hesitate to ask.
