After getting my very own camera for the first time in December, 2002, I started taking a photograph of myself every day. Then I used an inkjet printer to print out images taken that month on the same position of a single piece of paper. The images printed on the paper became blurred, darkened, and even turned black as a new image covered the previous one. On the first day of each month, I would use a new piece of paper and start the printing process all over again. Subsequently, I scanned the printed images of collected over 12 months separately and then photocopied the 12 pieces onto one single piece of paper. This results in the combination of the images within a year. This will be a life-long project.
In terms of subjectivity, I personally am impressed by the practice of non-self in Buddhism. This is the reason why I named this project The Denial One. Our faces are ageing and changing every minute of the day, which is what I mean by the idea that nothing lasts or sustains. Men’s faces change constantly and remain under a dynamic state. Therefore, without the heart and thoughts or ideas, the “existence” or “feelings” of an individual would be at a loss. Our existence does not happen in an objective world in which changes constantly occur. Rather, it is the constant changes occurring in the world which make us sense the passing of time and the presence of space. As each photograph is printed and overlap on top of one another, the newly-printed images do not completely cover the previous one perfectly. Traces due to dislocation still remain, which become the manifestation of the passing of time.

我自2002年12月有了第一部數位相機以後，開始規定自己每天自拍一張肖像。我用噴墨印表機將一個月的影像重覆印在同一張紙的同一位置上，每日影像上方的固定位置皆印有當日的日期。隨著墨水的疊印，肖像逐漸模糊、變暗，終至漆黑。每月初一更換一張新的紙，然後重覆噴印過程。之後將這些月肖像畫個別掃描，然後再將12個月的影像重複印在同一張紙上，得到的影像就是一年的肖像畫。這將是一個終生的計劃。
關於主體性的問題，我個人傾向（誠服）佛教的無我觀，這也是為什麼我將此計劃取名為「日日非」，我們的面目其實分秒片刻都在衰老與變化，這是所謂的無常，但是人的面目其實只是一個相續流變的相貌而已，若沒有心的辨識與觀念的認定，主體的「存在」與「感覺」並不會持續存有。我們的存有，事實上並不是有一個客觀的世界，讓我們去經歷無常；而是因為無常才讓我們感覺有時間流過、有空間存在。在重覆噴印每日自拍影像及拍照日期時，一定會發生輕微的錯位與墨水的重疊，這種錯位與重疊正好可以顯現出時間的變化。
