However, obviously, his attitude to life is not purely sensory, autistic, negative or cynical, even not neutral. At least, according to the painter's statement, the motivation of the concern is "re-propose the issue of interaction between people and society and the new objective for reflection", to show an ideal of "overcome loneliness, overcome negative, overcome impetuousness."(Deng Jianjin's Readme). I think basing on this starting point for thinking, he keeps the proper distance with the new generation art whose attitude to life is straightforward, graphic, artificial and evasive.

但很明显，他对生活的态度不是纯感官性的、自闭的、消极的或泼皮式的，甚至也不是中性化的，至少，按照作者自己的说法，这种关注的动机是为了"重新提出人与现实社会的感应问题和新的反思对象"，为了展示一种"战胜孤独、战胜消极、战胜浮躁"的理想化的东西，我想，正是在这个思维起点上，他与那些平铺直叙、图解化、矫饰的逃避式地对待生活的新生代艺术保持了应有的距离。
