Meaning of "It is not gonna work"
Here is the story:
One evening sereval days ago I was waiting for the subway to go home. Because I had been overworked for many days and my daughter was catching a fever that day I wanted to return as fast as possible, I squeezed in the train which seemed to have no space for even one person just at the moment the door was closing. Then I heard a voice from behind:"Oh, no, it is not gonna work." It was a foregner, who is about 50 years old. I felt kinda embarrassed, but kinda touched as well. I thought the meaning is "no need to hurry, you are not going to work. It is home instead." It was my first time to feel the caring from a stranger in such a rush hour in such a traffic-congested Beijing. Most time all people are just bowing their heads watching the cell phones. Nobody cares for others.
Then I posted a post in my wechat. But my friends doubted that I made a mistake. The meaning should be "Oh, no, you cannot get on the train."
I appreciate if somebody can confirm this for me. Thanks in advance!
