Gao Guang called Danny to report that he would be leaving the factory for a transport mission in Johannesburg, and then naturally asked, "Do you know what's happening in South Africa?"
In South Africa, Gao Guang had no channels of his own for news, so the only way for him to find out how the situation might develop was to ask Danny.
Since the Warfire Group had operations in South Africa, Danny should be concerned about the situation there.
"Do you know the former president, Jacob Zuma?"
"Yes, I didn't know before, but now I'm aware of who he is. He resigned in February this year, and then he faced many charges. The situation for him isn't looking good now."
