During the 19th century, the house was inhabited by a migrant Chinese (sometimes Japanese) family. The father worked very hard and came back late at night every day. One day, he came back earlier and was surprised to hear strange noises coming from his and his wife’s bedroom. He went there and fount his wife in bed with a lover, irate, he grabbed a knife and hacked them both up into pieces. When his kids got home, he decided to kill them as well since he saw no feasible explanation of his deeds and he didn’t want them to hate him. After that, he committed suicide.
While property records show that a Chinese family did indeed live in the house during the early 19th century, there is no proof that the above events transpired. This story’s popularity however could be attributed to lingering xenophobia, staring from the mid 19th century to the early 20th century, there was a very large wave of Chinese migrants to Lima. These immigrants were brought to Lima under false pretenses of wealth and opportunity when in reality, they were brought to collect guano since there was a dearth of cheap labor in Lima (the remaining Africans who were brought over as slaves were too few and the indigenous population had fled to the Andes to avoid being enslaved). These Chinese immigrants suffered horrendously and died by the thousands; however, there was a good number who survived the Guano age and established themselves in the city. In spite of their work which had brought an immense level of prosperity for Lima, these migrants were viewed with distrust by the Peruvians of European descent and were actively discriminated against. This version of the story is a vestige of that sentiment.
