What is the biggest reason why Gu Yan's framework is unpopular in the Fire Military Academy?

This play is still very interesting. I think Gu Yan's framework is very good. Why is it unpopular?

Retro style of the Republic of China, military academy theme of the Republic of China, passion and inspiration, vitality and youth, patriotism. When these elements collide, the launch of the Fire Academy adds a different color to the fiery summer file.

On August 6th, The Fire Academy, produced by Entertainment Film, iQiyi and Tencent Film, with JUNG WOO as the chief producer and artistic director, directed by Hui Kaidong and starring Bailu, Soso, Toby Lee and Wu Jiayi, was exclusively broadcast in iQiyi, which attracted wide attention.

Xie Xiang, a kind and just girl, joined the army on behalf of her brother, disguised as a man, and entered the army Wujiangtang to study. She became a classmate with the cynical rich boy Gu and the calm and steady Shen Junshan, and gradually developed into a comrade-in-arms fighting side by side. Under the strict and cruel training mechanism of the military academy, Xie Xiang not only tries to hide the secret of dressing up as a woman, but also overcomes all kinds of inconveniences in life as a military academy woman. More importantly, she should overcome her weak constitution, strive to complete all the training in the military school and graduate smoothly.

In this process, Xie Xiang and his classmates and friends experienced a series of great events, which also triggered a series of ironic stories. In the end, Xie Xiang not only achieved excellent results through her unremitting efforts, won the respect of her tutor, but also captured the hearts of two outstanding male students. After that, the Japanese army sent more troops to the northeast, and Jin, who worshipped Shen Junshan, returned from overseas to serve as the president of the Japanese Chamber of Commerce. A series of intrigues followed. With the help of his classmates, Xie Xiang struggled with the Japanese, grew up in a pool of blood, shattered Jin's plot, and finally came together with Gu.

Rough advice, hope to adopt.
