After the Qing court entered the customs, there was a slogan when the dressing order was issued, which was "Leave the hair headless, leave the hair headless". In other words, all Han men (except monks) must grow their hair according to Manchu hairstyle (that is, shave off the first half of their hair) to be obedient, otherwise they will be regarded as resisting the Qing court and killing without forgiveness. At that time, I don't know how many people lost it because of rejection. Therefore, in the Qing Dynasty, at least before the Opium War, it was unthinkable that Han people (except monks and armed rebels who deliberately opposed the Qing court) dared to grow their hair in the first half of their heads as you said, which was a great crime of losing their heads! What you said about some Hong Kong and Taiwan films may be that some writers, directors and producers don't know much about history, or they are not serious about history, or they are trying to accommodate some stars (in fact, I also think that hairstyles are ugly, and some stars may feel the same way), so this situation is simply unimaginable in the reality of history of qing dynasty at that time! ! !
In fact, you can easily find a lot of information about changing clothes in the Qing court by typing "changing clothes" or "changing clothes without leaving a head" in Baidu Encyclopedia. I found a detailed introduction of this information, which is called "changing clothes". The link to this information is as follows:
