Reference: （彝语）杀只鸡，你死了我开心
"Slaughter a chicken as an offering to thanks gods" is a common expression in Chinese, meaning: "something to celebrate for; something to thanks gods for"

In Cantonese, it is 要劏雞還神 

Example: 如果你死咗，我就要劏雞還神 ( if you died，I will have to celebrate / thanks the gods )

The wording differs from dialect to dialect. For example,  要劏雞還神 in Mandarin would be 要殺雞酬神 and in other dialects, including Yi,  屠 or 宰 may replace 劏 or 殺; other animal may replace chicken, but the basic premise would not be too far apart in writing.
