In this talk, we will investigate the long time behaviour of damped Klein-Gordon equation in the energy subcritical case. In fact, we will establish the soliton  resolution for this equation which means that the global bounded solution evolves into the super-position of moving solitons. Moreover, we will give some further description and classification results about the 2-solitary waves. The talk is based on joint works with Ze Li, Raphael Cote, Yvan Martel and Xu Yuan.
