Who is the hidden boss? Huang called him a master, while Du was a junior in front of him.

Huang said he was a master, while Du was the hidden boss of the younger generation in front of him. Actually, it's Zhang Renkui. In the early years of the Republic of China, Zhang Renkui was the leader of green gang, but at that time, due to the influence of warlords, only green gang led by Zhang Renkui finally became more and more powerful and became a real mobile phone in Shanghai. According to this generation, he is one of Du's grandfathers.

Green gang also has strict seniority. By the time of the Republic of China, green gang's disciples had developed into five religions and four classes in Datong. By the time Du became a famous tycoon in green gang, he was the only disciple of Datong at that time, while Du was only a disciple of Zhongdong in green gang, so he was the elder of Du's grandfather.

Zhang Renkui had great power at that time, and he also had his own people in the army. Moreover, when Zhang Renkui made friends, there was a rule that anyone who interacted with him was powerful, even if he accepted an apprentice, he should have a background. Therefore, Huang has achieved such a status and is qualified to be called a master. Nominally, Du once worshipped Huang as a teacher, so Du's position in front of him was even lower.

When Huang and Du get along, these tricks are actually the rest. Even people from the military came to Shanghai and had to take the initiative to please and curry favor with Zhang Renkui. Although Zhang Renkui was no longer in power when he was old, Zhang Renkui had a high prestige. As long as something important happens on the beach, Zhang Renkui will be invited to uphold justice.

Later, Zhang Renkui was always pestered by the Japanese in his later years. Although the Japanese put forward very good conditions, combining hard and soft, Zhang Renkui still sticks to its own bottom line and principles, and would rather die than cooperate with the Japanese. However, due to weak health in old age, he died after several head-on conflicts with the Japanese.
