This place is too poor, the winds of reform and opening up can't reach here, the mountainous areas are closed off to information, and the people here value boys over girls. Girls born here are often abandoned, not many grow up, and the few who do are reluctant to stay in the village, desperately seeking to marry outside. This has led to many bachelors.
Vicious cycle, looking down on girls, giving birth to a bunch of sons.
These people are lazy and unwilling to go down the mountain to work, guarding their barren land, having no money, becoming bachelors, unable to find wives. So they pin their hopes of procreation on these "reproductive tools" they buy with money.
Seeing Xiao Qian and Xiao Yu, several old bachelors swallowed their saliva.
