Pulsar Timing Array (PTA) uses nature-provided millisecond pulsars as ultra-stable clocks allowing to detect gravitational waves (GWs) in the nano-Hz band. In this talk, I will introduce the operational principles of PTA. Then I will describe the latest results reported by regional PTA collaborations under International PTA umbrella. Finally, I will give some plausible interpretation of the observed signal.
