Computer Chinese chess programs usually a passive opening book in the opening phase. One important issue is early drop-out due to some moves rarely played. This thesis focuses on improving this situation. We use Job-Level Alpha-Beta Search (JL-ABS) to verify an opening book that is based on a tree structure, and propose a method that actively adds nodes to the tree. The method is run on a job-level computation system to increase the construction efficiency. The experiment result shows that more moves we add to an opening book, less serious the early drop-out situation is.
