The discussion of this issue is barely involved with how the spirit of Utopia and individual value that exist naturally in the Western abstractionism have decayed and weakened while it is developed in China style. Instead, it concerns the gains and losses of 'nationalizing' the oil paintings, safeguarding cautiously the inherent spirit of the modern tradition, which, together with non-painting avant-garde art and figurative paintings, constitutes the three-pillar fine art forms.

这个问题值得讨论之处，已不再是西方抽象主义原本具有的乌托邦精神和个人价值，应如何在迁就地"国化"的过程中衰减和削弱，而是应联系到油画"国化"的得失，警惕地守护这个据说与非绘画性前卫艺术、具像绘画等鼎足而三的现代传统的内在精神。
