In 615 when Emperor Yang of the Sui Dynasty (581-618) was besieged by the Tujue's army, Li volunteered to lead a rescue operation thus making quite a name for himself at the age of sixteen. In 517, seeing that the Sui regime was near collapse, he encouraged and assisted his father in plotting the establishment of a new dynasty.
