Each sect has three kinds of things to collect, which are distributed in various sects in disorder. For example, the task of Emei Sect is to let you find lost things, expensive necklaces and so on. You should see clearly what it tells you to look for, and then catch that project. Let's say it lets you find the lost orb, but if you rob that precious necklace, the system will realize that you didn't take the task.
