就是脸花了，变脏了的意思

NO,there is 46 alphabets in Chineese , if you don't know how pronounce "你好"， you can directly say hello , we all understand it in China !

uh……yes ,i have used to google to trsanlate it .because i can't use Japanese language to say something by myself !

I think it's hard to say ,I suggest you should remeber more words about a word ,for example.名——名词、名字、名气 and 姓名、出名 and so on. it's the same to we when we are children .
