Yusuf Zuck had two mobile phones on him; he turned one off, but the other was still active, so the fact that the Petty Family couldn't reach him didn't mean others couldn't find him either.
Of course, the Petty Family pulled out all the stops, aiming to locate Yusuf Zuck during his time in Hong Kong to have him lend a hand, helping them resolve a major issue.
Yusuf Zuck guessed that the Petty Family's trouble was serious, which is why he decisively turned off his phone, because he had no wish to get involved in that kind of…that kind of underworld conflict. How he threw his weight around in society, or squandered money in the business world didn't matter, but he knew that once he got involved in the Petty Family's strife, it would never end.
Eventually, it would entangle more people, and he would make even more formidable enemies; thus, he kept his distance, refusing even if the Petty Family offered him a lot of money.
