Energy transport in quantum spin chains is considered. We first discuss the Heisenberg chain with weak perturbation. In the region where the field theoretical treatment is valid, an anomalous transport still exists in the presence of the Umklapp term. We next consider the large perturbation where trivial symmetries does not exist. In this case, the Green-Kubo formula converges, and the normal thermal conduction appears.
