At present, Characters Collection in Chu Area（《楚文字編》） (called CWZB in later content) is not only just an important ancient writing dictionary, but also a high-level academic bookmaking because of its appropriate stylistic rules and layout，abundant contents and easiness to use. However, any academic achievements have historical limitations. After CWZB came out, it had been revealed a lot of defects from the perspective of current situation and the status of unearthed study of Chu literature. The main disadvantage is missing graphemes from Bamboo Manuscripts Deposited in Shanghai Museum (《上海博物館藏戰國楚竹書》 (called SBJ in later context)). SBJ is the most important written material after Bamboo slips from Guodian Tomb（《郭店楚墓竹簡》）. SBJ is published in succession since 2001.The total number of characters are up to 20000.Obviously overall presents about Characters collection in Chu area will not be intact if Characters from SBJ are not embodied. We concluded about 900 newly-supplemented characters with SBJ making up CWZB. Those newly-supplemented Characters show the following research significances: 1) bringing forward existence of some Characters; 2) enriching meanings of some characters with the reference of new manusciptionmanuscripts; 3) amending some errors in CWZB with the reference of newly-supplement Characters; 4) numerous newly-supplemented characters show their corresponding relations between themselves in Chu area.
