During the campaign, on one occasion, Li Jing rebuked Gao for arriving late, but did not punish him. Gao nevertheless was displeased with Li Jing's rebuke, and he and the official Tang Fengyi (唐奉義) accused Li Jing of plotting treason. The matter was investigated, and the evidence was found lacking. Gao and Tang were accused of false accusations and exiled, notwithstanding pleas by others that Gao contributed to Emperor Taizong's ambush at Xuanwu Gate against Li Jiancheng. However, from this point on, Li Jing refused to receive guests, and he even did not see his relatives often.
