We study the charmless two-body and three-body 
decays. We obtain 
to agree with the recent LHCb measurement. However, we find that 
is unable to explain the LHCb observation of 
, which implies the possibility for other contributions, such as that from the resonant 
decay with 
as a higher-wave baryon state. For 
, we show that 
, which are consistent with the current data of 
, respectively. Our results also support the relation of 
, given by the previous study.
