Cool Kanji

I was asked about some Japanese language questions.
I am glad that you are interested in Japan and  Japanese language.
I knew that the tattoos of the kanji were popular from the website.
And I knew that a lot of wrong kanjis were used.

The example of the tattoo of the wrong kanji.

巨乳 →× pretty woman. ○ large breasts

放火魔 →× firefighter. ○ pyromaniac.

不景気 →× Bad words to feel cool. ○ a recession; a depression; a slump

冷 →× cool. ○ Temperature is low.

If you want the tattoo of the kanji,You should talk with the Japanese or Chinese.
