Online litigation is a breakthrough to the spatial limitation of offline litigation,and the asynchro-nous trial mode is a deconstruction of the time limitation of online litigation.Asynchronous trial is carried out in the form of staggered time and writing,which reduces the litigation cost of the parties and enhances the effi-ciency of dispute resolution,and at the same time,it also has a great impact on the traditional civil litigation ju-risprudence and litigation culture.In particular,the non-compatibility between asynchronous trial mode and direct speech principle leads to the generalized application of written testimony and the lack of circumstantial evidence,increasing the difficulty of discovering the true case,but being contrary to the original intention of asynchronous trial mode.Therefore,at this stage one should be vigilant to the risks that may be brought by forcing the application of asynchronous trial mode.In the case that the legitimacy of asynchronous trial mode cannot be proved through legal hermeneutics,compromise and concession should be made to this kind of irrec-oncilable conflict.On the basis of making it clear that the asynchronous trial mode prioritizes efficiency,the deepening of the asynchronous trial mode should be promoted by improving the design of the rules for the asyn-chronous pre-trial conference,implementing parallel synchronous and asynchronous trials at the trial stage,and constructing a system for late loss of rights,an interactive conversion programme for the proceedings,as well as perfecting procedural safeguards,such as hardware and software technology.
