In China it is pretty standard to use 70后(后=after), 80后 (born 1980-1989), 90后 (born 1990-1999) etc to describe the age of a person. Instead of "he is forty-some

In China it is pretty standard to use 70后(后=after), 80后 (born 1980-1989), 90后 (born 1990-1999) etc to describe the age of a person. Instead of "he is forty-something", you say "he is 70后". "Born in the 70s" might be a little lost in translation.
