Because this day is close to China's traditional Spring Festival, the firms tapu direct debt collecting in people's homes. So the gift of vinegar pickled garlic indicated debt collection.

In some areas and families, there is a method of making "Orthodox" Laba garlic, using specific purple garlic and rice vinegar in the eighth day of lunar December.
Source of color
The abundant sulfur compounds in garlic are responsible. These are normally kept separate from an enzyme (alliinase) that can act on them. However, acidity damages the cells of the garlic, allowing the enzyme to cleave the sulfur-containing compound alliin to release reactive thiosulfinates. These then react with each other and with amino acids found naturally within cells to make pyrroles, clusters of carbon-nitrogen rings. These rings can be linked together into polypyrrole molecules. Ring structures absorb light and thus appear colored. The exact color depends on the number of pyrrole rings and the amino acids involved. When four of the pyrrole rings have been joined together, the resulting structure is very like phycobilin, a compound used by algae and some bacteria to capture light for photosynthesis. In laba a mixture of compounds are present, resulting in the green-blue colour. The pyrrole pigments are safe to eat.
