英语翻译
kill two birds with one stone
one sings and other joins in
difficult to move even one step
out of ten attempts,nine will be successful
It's better to see once than hear a hundred times.
at sixs and sevens
six of one and half-a-armed monster
be always the same from first to last
only one chance of life in ten

一石二鸟
一唱一和
举步为艰
十拿九稳
百闻不如一见
