帮忙测试一下我们的 demo 系统（有lottery^-^）
现在我们课题组开发了一个电子产品搜索推荐系统，希望收集一些真实的用户反馈，所以在这里我们同学们在空闲之余帮忙体验一下这款系统（用户可以选择购买电子产品，例如相机，笔记本）。
下面是大体的介绍（其中的500元港币我们可以换算成其他货币交付）
============================================================
Dear Students,
We kindly invite you to take part in our experiment, which aims at studying how users search for products (e.g., digital cameras or laptops) in online stores.
To make it worth your while, the first 60 participants who successfully complete this experiment will be entered into a lottery for three prizes (each is in value of 500 HKD). It could be you!
If you are interested in, please click the following link to start the experiment (the whole process will take around 30 minutes):
