Abstract
We extract key information of dark energy from current observations of BAO, OHD and , and find hints of dynamical behaviour of dark energy. In particular, a dynamical dark energy model whose equation of state crosses is favoured by observations. We also find that the Universe has started accelerating at a lower redshift than expected.
