In the scorching sun of Singapore in 2024, when Lin Zhaoran was taking care of his grandmother's funeral and sorting out her belongings, he accidentally discovered a yellowed diary written with "A Diary of Making a Life in Nanyang in the Thirty-sixth Year of Guangxu". The mysterious words in the diary such as "Kuri Husband" and "Fu Shou Drug Shop", as well as the shocking blood-painted skull patterns, are like a key, quietly opening the door to the family's long-standing secrets, and planting the seeds of searching for the truth in his heart. It happened that the National Museum of Singapore was collecting historical materials on the coolie trade from 1910 to 1914. Lin Zhaoran went there with his diary and learned from historical researcher Dr. Chen that part of the truth about that period of history, which was full of blood and tears of Chinese workers, had been deliberately downplayed. In order to uncover the dark past buried by time, Lin Zhaoran embarked on the path of pursuit. He traveled through old neighborhoods in Singapore, and pieced together the tragic experiences of Chinese workers during the colonial period from the memories of the old man in the grocery store, the dusty archives of the National Library, and the narratives of old professors: In 1910, countless Chinese workers with the dream of "going to Southeast Asia to make big money", such as Chen Ah Fu, Lin Ah Shui, Zhou Mingyuan and others, were deceived into Singapore, but became "piggy Chinese workers." In the rubber plantations, they were subjected to sixteen hours of high-intensity work and whipped by supervisors; the colonists set up a sweet trap of the "Fu Shou Drug Shop", using free and promotional methods to get the workers addicted to drugs and drain them of their hard-earned money. Under drug addiction and oppression, the Chinese workers either lost their families, killed each other, or rose up to resist. The Chinese workers headed by Chen Afu secretly collaborated, hijacked ships to deliver certificates, launched strikes, and composed a tragic song of resistance in blood and fire.
