Based on the summarization of the relative cases，the principle of good faith in German civil procedure can be concretized into four groups，namely the forbiddance of the fraudulently process Situation，the estoppel，the forfeiture of the procedural rights and the forbiddance of the abuse of the procedural rights. The analysis of the concretization of the principle of good faith in German civil procedure may contribute to its proper enforcement in Chinese civil procedure.
