Let's look for example at the work of the mainland Chinese artist Niu Bo, who had a show at Z last year. His work incorporated ideas from Tibetan Buddhism, and was "very free and liberated." This is precisely the artistic viewpoint Zhang wants to express.
以去年「Ｚ」畫廊展覽中國大陸藝術家牛波的作品來說，牛波的作品融合了密宗思想，非常「自由解放」，正是張張想表達的藝術觀。
