The nickname "Xiao Qiang" originated from Stephen Chow's movie.
In the 1993 movie "Tang Bohu Spots Autumn Fragrance", Tang Bohu, played by Zhou, pretended to be a poor man who sold his body to bury his father in order to enter Washington as a handyman. All the dogs died on the spot, so Zhou had an idea and called the cockroach that was accidentally trampled to death "Xiao Qiang" and cried for it as a pet he had raised for many years.
In addition, in Stephen Chow's movie "The Dead Man", Zhou's character pointed out that an innocent prisoner murdered his friend "Xiao Qiang", but this "Xiao Qiang" turned out to be not a human being, but just a human being. A cockroach.
Extended information:
The reproduction of cockroaches is a combination of sexual reproduction and asexual reproduction. A mature female cockroach can produce an ootheca containing 14 to 40 eggs every 7 to 10 days. The ootheca is a colloid and hatches between 20°C and 37°C.
The higher the temperature, the shorter the incubation time. At a constant temperature of 30°C, it only takes 20-30 days, and it can last more than three months. A female cockroach can breed nearly 10,000 offspring a year. , up to 100,000. Female cockroaches can also lay eggs under extreme conditions when there are no male cockroaches.
In other words, after many female cockroaches mate once, they become hermaphrodites and can lay eggs continuously without mating.
