"Indeed!" Yingying's father agreed, and at that moment, he saw the interesting knowledge display board hanging next to the glass curtain wall. The composed middle-aged man's face unexpectedly broke into a childlike smile, "Hey, look at this, so red pandas stick out their tongues because their tongue is a sensitive detector that can smell predators. I used to think they were just being cute."
Liu Xueqing couldn't help but laugh, "You're so funny, which animal sticks out its tongue to be cute? Other animals won't stop eating it just because it sticks its tongue out."
Although she didn't know this piece of information either, it didn't stop her from joking about Yingying's father, who chuckled "heh heh" without saying a word.
