First of all, Shen Yue kept his mouth open when taking pictures. The reason lies in the middle of her face, and Shen Yue's nose is relatively low, so when she smiles, there will be obvious depression in the middle of her face. Besides, her mouth is wide, her lips are thick and her teeth are crowded, so from the front, her mouth protrudes forward.
On the other hand, it may be because there is no training, and compared with other stars, they will have no sense of lens and behave amateurishly. When Shen Yue spoke, his mouth drooped and his head leaned back, which easily exposed the defects of his teeth and face. But she still insists on being herself and maintaining her personality, although her appearance has no advantage over others. Due to the depression of the temple, the expansion of the zygomatic arch and the wide jaw, Shen Yue's face is not smooth, like a polygon. The mandible is almost as wide as the cheekbone, which leads to too much white space on both sides of the cheek, making the face unusually short and wide.
Finally, Shen Yue has slight symptoms of crowded dentition, and she has a big square tooth. Her expression habit of pulling down the corners of her mouth is also affected by dental problems, which is due to her physical quality, not because she looks good.
What do you think is the other reason why Shen Yue opened his mouth when taking pictures? Welcome everyone to add enthusiastically.
