This kind of old-Shanghai-style barberís in Hong Kong
has been gradually replacing by western-style salons.
Right after you sat down, the barber will start using an electric shaver trim off all your excess hair.
Then he will switch to a pair of comb teeth scissors and roughly cut out the shape with some layers.
Finally he will give a final touch with a smaller electric razor and if necessary give you a straight-razor shave.
It normally takes less than 30 minutes to complete the whole process.
This barber's charges you only HK$30 (US$4) for the service.
It is very different from the western-style salons,
which start with shampooing, head massaging and then bit-by-bit hair trimming.
The whole process takes much longer time than the Shanghai style.
