What do you mean by watching the plane?

Fei's explanation: I didn't go to the appointment as agreed in advance, or I didn't honor my promise.

Feitian Pinyin: fong3 fei 1 gei 1 (Cantonese Pinyin)

Allusion: In old Hong Kong, one day, there will be planes flying. This is the first time in the history of Hong Kong that there are planes to see! And it is a seaplane! Hong Kong people are expecting: someone wants people to see the plane! On the first day, because of the hurricane, it couldn't be opened, and everyone was disappointed. The next day, the sky was clear and everyone thought it was worth watching, but the plane teacher and students were sick and had to put it off until the third day. On the third day, I noticed that the engine of the plane had an accident and could not be repaired. Then-bye (it should be over)! So people use flying to describe the behavior of those who say they want to do it but don't do it.

Synonym: stand up, stand up.

The derived "pilot" and "airplane king" are also often used to refer to people who don't keep appointments on time or often break them.
