What does Huapofu in Pumiao Town, Nanning mean by sending a packet of millet, a red thread, a box of matches and two coins?

My literal feeling is that there is food (rice fills the stomach), marriage (similar to the red line of the old moon), talent (the homonym of matches) and wealth (coins are money, but 20 cents is nothing). Generally speaking, it is a good wish. The behavior of Huapo giving porridge for free itself extends the blessing of "porridge" (vernacular is blessing).
