That day，I gently placed my child at my father's doorstep，then turned around and ran. He looked down at the child，then looked up and around，and suddenly his eyes lit up. The surprise came so suddenly that he didn't have time to say a word，but his lips curved into a smile first. Leaving my baby at my parents doorstep and running to see their reaction. It was as if time had forgotten to move forward，leaving only a father. "This is crazy！"struck by pure happiness. Leaving my baby at my parents doorstep and running to see their reaction.
