Brother Chen Haohao, a migrant worker who first arrived in Shenzhen, with a gangster spirit and full of ambition, ran rampant in this modern jungle where opportunities and traps coexist. From moving bricks at the construction site to setting up a stall in the night market, from being deceived by a black intermediary to being accidentally involved in the whirlpool of underground banks, he relied on his unyielding determination and bottom-level survival wisdom to struggle to survive in the gaps between steel and concrete. When the old Jianghu brothers and the emerging capital forces collided fiercely in this hot land, Brother Hao discovered that if he wanted to truly gain a foothold in this city, fists and loyalty alone were far from enough. This is a legendary story about grassroots counterattacks, the ups and downs of desire, and a man's search for his place in the tide of the times.
