Thanks to modern technology - wide-field camera, high computing power, massive data storage, and robotic observation - it is possible to obtain thousands of asteroid light curves within a short period of time. Therefore, several important applications can be conducted on asteroids in a more comprehensive way. For instance, the interior structure can be studied through the spin-barrier, the mechanisms changing asteroid spin status can be learned through the spin-rate distribution, and the discoveries of binary asteroid, etc. Moreover, the super-fast rotating asteroids, a kind of odd objects against the current rubble-pile structure, can refresh our understanding of asteroid. I will talk about our asteroid time-series survey using wide-field facility, such as the PTF/ZTF, the PS1, the Xuyi observatory and the KMTNet, and what we have learned so far.
