清代文人、书画家郑板桥原本治过一方自用印章,印文为“徐青藤门下走狗郑燮”,此后袁枚、齐白石、余秋雨等历代诸多著名文人、书画家都曾明确地说过确有其事。可是自上个世纪90年代以来,不时有人考证,认为此事属于子虚乌有,并以此批评袁、齐、余等人,这就形成一桩悬案。笔者经过查阅《郑板桥文集》全书以后,发现了充足的根据,有力地证明确有其事,因而最后断定:此案自此可以决矣。 Zheng Banqiao, a literati and painter of the Qing Dynasty, originally had a seal of his own use and the seal was “Zheng Xie, a walking dog under Xu Qing Teng”. Since then, many famous writers and calligraphers of various historical periods such as Yuan Mei, Qi Baishi and Yu Qiuyu have clearly said that they did. However, since the 90s of the last century, people from time to time have made a research on this issue and considered it to be non-existent and criticized him as Yuan, Qi and Yu et al. This resulted in a pending resolution. After the author of “Zheng Banqiao Collected Works,” the book found a sufficient basis, effectively prove that there is a real case, and thus concludes: the case from now on.
