Unsigned: Everything you hope will succeed, which is gratifying. If you want to find a job in the public, you should work hard, just as Dong Zhong is not afraid of hardship when looking for his mother.
If you want to take an examination of civil servants, you meet the word "from the public". Signing a contract means that if you work hard, that is, you work very hard, as if you were desperately looking for your mother, then your hope will come true. Bottom line: The future is bright and the road is tortuous.
