Why are fingerprints related to people's fate?

There is a Chaoshan folk song about fingerprints and the fate of life, which is widely circulated and has many versions. The version is like this: "One snail sits up, two snails walk away, three snails have rice to cook, four snails have rice to cook, five snails have five granges, six snails hurt their hearts, seven snails have seven benefits, eight snails beg for food, nine snails are safe, and ten snails are squires."

There is also a song sung by a girl, and the last two sentences are: "Nine snails are poor, and ten snails are wives." In Chenghai area, there is such a variant: "Seven snails cut horsegrass, eight snails sell beds, nine snails sell post offices, and ten snails beg for food." In some places in Chaozhou and Jieyang, it is also sung as "three snails cooked without rice, four snails cooked without rice", which has completely different meanings.

The word "snail" in Chaoshan proverb is "cymbal", and the pronunciation of Chaozhou dialect is Luo, which refers to the fingerprint in the shape of a bucket. Palmistry has a long history Generally speaking, people's fingerprints can be divided into two categories: circular bucket pattern and non-circular dustpan pattern. Bucket pattern is commonly known as "snail" and dustpan pattern is commonly known as "dustpan". Palmistry also believes that the number of snails is related to human destiny.
