Pion string formation and decay at LHC Pb-Pb collisions are studied. It is shown that If the SU(2) chiral phase transition in QGP is really taken place in a second order the pion string will be produced and subsequently decay. The main phenomenon is that there are a large number of pions with mean momentum of about 69.1Mev. This prediction is a new phenomenon.
