The behind-the-scenes can be scenes during filming. The full name of NGNG is NO GOOD. During the filming process, I often hear the director shouting NG, which means that it is not good and asks the actor to do it again. It can also be some interesting things that happened to the staff and actors during the filming break.

1. White and soft flowers. Mostly refers to catkins. "Ode to the Willows" written by Emperor Liang Jianwen of the Southern Dynasty: "When the catkins follow the birds, the wind blows the branches repeatedly." Song Liuyong's "Mishen Yin" lyrics: "I feel that the spring is dying, and the catkins are gradually floating." Chen Weisong of the Qing Dynasty "Yongyu Le·Send to the Garden" "Return to Wuxing and Dan Xinyun" lyrics: "Singing wildly on one's arms, turning around and roaring, everything always follows the tidbits." Guan Hua's "Hometown": "The crowds scattered on the fields are sowing seeds in the flying tidbits."

2. Metaphor for various interesting bits and pieces of news. Often used as headlines for news reports. Xiao Qian's "A Faded Photo Album·A Traveler Without a Map": "The liaison officer holds a press conference every day, but what he 'reveals' are only tidbits, such as the recipes at the Big Three's luncheon." For example: Highlights from the conference ; Stadium Highlights.
