在我们开始之前，我希望您能理解，就是我们会做录像，我们还是要让您知道您

Before we start, I hope you can understand that we will make a video. We still need to let you know that you have the right to know. This is for our research and internal use, because we need to record all the information you provide to us. But I can’t remember it now, so I need this video. But we guarantee that it will be kept confidential for internal use during the use process. At the same time, after this research project is over, we will delete it. Please delete it.

在我们开始之前，我希望您能理解，就是我们会做录像，我们还是要让您知道您有知情权，这个是我们调研用的，内部使用的，因为需要记录你提供给我们所有的信息，但是肯定现在记不下来了，所以需要这个视频。但是我们保证就是在使用过程当中，肯定是内部使用会保密的，同时在这一次的调研项目结束之后，我们会把它就是删除了，请您删除。
