Zach was introduced to the executive management of the Liu group as Old Madam Liu's long lost grandson. They were all surprised by the news because it was so sudden. Who would have thought the infamous old lady had two grandsons that were a General before they left their active military duty? Many people knew Zach because he had been in the news several times as one of the country's heroes, and as an esteemed General who was held in high regard by his subordinates.
Old Madam Liu initially wanted to hold a grand banquet for Zach as soon as he changed his name to Zacharias Liu, but Zach refused because he wanted to maintain a low profile as much as possible.
