I think that the trio should not beat him up and tattooed parts of his body with vulgarities and other symbols even though Li disobey their orders. Beating people and tattooing his body without Li's approval is way to much. Moreover, Li Qian claimed that it was Li who wanted the tattoo on his body. Who would like his or her body to be tattooed with parts of the body and with vulgarities and other symbols? I believe no one wants such a tattoo on their back.
Li, meanwhile, is said to be very worried that he cannot find a proper job because of the tattoos. However I feel that employers should not look at Li's tattoo on his back and not employing him. This tattoo isn't Li who did it willing, he was being bullied.Li should receive some compensation to allow him to get rid of the tattoos. Getting rid of tattoos is not cheap.
The trio were being arrested and i hope that the police should seriously look into the matter. This should not be allowed and they should punished them serverly. If there is more of such cases happening, it would create more problems to the society in the country. Tattoo guns should only be used by tattoo artist, otherwise they should banned the sale of tattoo guns everywhere in order to prevent such an incident from happening.
