Indeed, last night the tide had risen, and the sand was all moist. Some of the sea treasures brought in by the high tide would remain on the beach because they didn't follow the receding water. Treasure hunting by the seaside involved taking this opportunity to find the seafood left behind.
Carrying a basket, Mianmian was the first to find a seashell by the shore and tossed it into her basket.
Discovering there were many shells, she continued to pick them up, and before a while, she had separated from Charlie.
The staff had intended to follow Mianmian, but after following her for a few steps, they suddenly stopped and went to film Charlie instead.
The audience in the Live Broadcast Room found this scene very strange.
During a team activity like this, filming should normally be done in pairs, with an adult and a child together. It's not right to let a child wander off alone.
