Fang Shaokang told the driver to park the car below building B and wait.
They found their way by asking people for directions. The guard wouldn't let them in, hence the phone call to Professor Jiao. He managed to slip in a word of complaint regarding the black cat during the call. "Your cat used me, then wouldn't even lead the way."
After getting Professor Jiao's approval, the guard relented. He asked how Fang Shaokang came to know Professor Jiao's cat. Fang Shaokang gave some far-fetched reasons, after all, he was never going to admit to anyone that he did shows with the cat.
Fang Shaokang went on all his 'clear the head' trips on his own.
He did too many bizarre things that he didn't want people knowing. He himself didn't care about his reputation, but the Fang family did. His family would call him frequently to remind him to watch himself and not make a fool of the family.
