Around New Year 619, Li Mi requested Emperor Gaozu's permission to head east to persuade some of his former subordinates to submit to Tang, but once he left Chang'an, planned to restore his independence.
Omkring nytår 619 anmodede Li Mi om kejser Gaozu's tilladelse til at drage østpå for at overtale nogle af sine tidligere underordnede til at underkaste sig Tang, men da han engang forlod Chang'an, planlagde han at genoprette sin uafhængighed.
