Xu Hongfei often portray his Chubby Women sculptures as active and in motion. The idea of a woman being beautiful because she is in motion is a fairly new idea. This goes against the female ideal for several decades which was soft, dependent and domesticated. In some sculptures, the artist places his female figure next to structures which imply mechanization and function. Women are shown inside or interacting with structures which by its very nature implies movement, such as wheels, coils, staircases. Ode to Joy (2019) is a reflection of this, as the chubby woman is riding a bicycle with gestural movement. One of the wheels of the bicycle is on the surface of the ground, while the other is in mid-air. This makes the chubby woman not only looks suspended and athletic. On the other hand, the Chubby Woman in A Golden Dance (2019) is also seen in motion. The female is engaging be engaging in a lighthearted celebratory dance with a pig. The artist made this artwork during and for the Year of Pig. The pig symbolises prosperity, well-being, enjoyment and abundance. The similar poses between the pig and woman suggest that they share these positive connotations. In another work, Blossoming June (2018), three woman are running on a bed of flowers. Their gestures and expressions convey human passion and positivity. The name of this artwork is based on the nickname of Guangzhou, “Huacheng” which means city of flowers. In this city, there are perennial blossoms on the streets, with flower fairs and markets, which is said to have taken place during the Ming Dynasty. By conveying the three chubby figures running in “Huacheng”, the artist reinforces the idea that the figures themselves are blossoming and are in good shape and health.



許鴻飛的作品不但只是強調「肥女」的可愛，而他創作的雕塑中的藝術性亦是作品的亮點之一，例如他特別喜愛強調作品裡的戲劇性與張力。他的「動感系列」便是一個明顯的例子，肥女的表情都是誇張而生動的，她們的動作都是充滿勁道。而且許鴻飛往往喜歡挑戰難道甚高的肢體動作，並且在佈局裡多以對角拉力的結構為重點，令人看著感到雕塑中的人物是帶著激情，還有形成逗趣的效果。
許鴻飛喜愛宣揚快樂正面的訊息給觀眾，而他所刻劃的多數是日常生活動的小情趣，因為他認為人生活著就是要快樂。而且「藝術家之責任，乃自創風格，突出個性，俾眾周知……藝術，玩物也。藝術向求偉大，易失其本質。」他的藝術作品是以趣味和幽默作為注腳，這亦是他的個人藝術觀。
