Exploring the very early universe with CMB observations

In this talk I will introduce the historical developments of CMB experiments in the past decades. Thanks to the great​ ​developments in the CMB surveys, we have gradually stepped into the era of precision cosmology. By virtue of the high precision data, we are able to distinguish a number of theoretical modes that were designed to describe the physics of very early universe. I will give a brief description of inflationary and bounce cosmologies, and report on the recent observational constraints upon these models. After that, I will introduce the latest progress of the Ali Cosmic Polarization Telescope project.
