Before planning to go to the KTV, Bi Xia investigated Yu Du's associate Yu Hai's activities. His whereabouts were frequently unknown, but Bi Xia noticed that Yu Hai would come to a KTV called 'Long Ao' every Friday and then disappear for the entire night, only reappearing the next evening.
It's easy to speculate traditionally that Yu Hai might have a mistress or someone like that in Long Ao, and they'd stay until the next evening. However, Bi Xia couldn't find anything here, let alone a woman.
So Bi Xia simply chose this place for KTV, and with Xia Nian being here too, Bi Xia wasn't worried about being discovered and questioned by Yu Du's people. After all, Shixia Trade and Yu Du were already at odds, and her main purpose here was to see what the leader of Yu Du was like.
