The outfit worn by Chen Xiao, at first glance, seems to be almost the same as the physical education teacher's. If it weren't for his handsome face adding a bit of unique charm to it, this outfit would probably be drowned in the ordinary. 
The design of this outfit seems to pursue a simple and elegant style, but it may be a little conservative in color and style, resulting in it not standing out among many outfits. And Chen Xiao's appearance and temperament undoubtedly add a touch of color to this outfit. His elegance complemented the simplicity of the outfit, giving it a different brilliance on him. 
From another point of view, this outfit also reflects a common pursuit of modern people in wearing: comfort and practicality. As the embodiment of sports, physical education teachers are often representatives of this style. Although the outfit chosen by Chen Xiao is simple, it exudes an uninhibited natural beauty, as if telling his attitude towards life: not to pursue flashiness, but to seek truth and freedom. 
However, the ordinariness of this outfit is also its charm. In this fast-paced era, people tend to be tired of chasing trends and ignore the beauty of simplicity. Chen Xiao's outfit reminds us that real fashion is not necessarily the accumulation of big brands, but the simplicity and naturalness that can make people feel comfortable. 
To sum up, although Chen Xiao's outfit seems ordinary, it actually contains rich connotations. It not only shows Chen Xiao's personal charm, but also reflects the aesthetic pursuit of modern people in dressing.
