The main reason is that the homonym of gourd has both the auspicious meaning of "Fu" and the auspicious meaning of "Fu". Gourd, in particular, has two important functions, one is to cure diseases, and the other is to turn evil spirits into good fortune. Feng shui gourds hanging on doors and around kitchen stoves are some flying stars related to diseases, which can help family members' health. Tie the gourd with a red rope, which can be hung on the bed or in a more auspicious position in the house.
The gourds hanging at the door are usually colorful, including red, blue and green. Each gourd has its own meaning, expressing special good wishes. Gourd in Qing Dynasty has an irreplaceable position in China culture. For example, gourds are used as mascots at home. When the two families hold a wedding together, the groom's family also puts the gourd as a gift symbolizing blessing, prosperity and good luck at the door of the new house to show harmony and prosperity.
The location of the gourd:
From a scientific point of view, it is more appropriate to hang the gourd on the door or by the door. Gourd is a kind of decoration, which is beautiful everywhere, and can create a relaxed and happy atmosphere for the family. From the perspective of geomantic omen, the gourd is best hung on the window frame, on the right side of the door frame, and it must be under the eaves, meaning "double circle" and "boundless prosperity".
Gourd can also ward off evil spirits. If there are some buildings or places with bad atmosphere near the house, you can hang one or two gourds outside the gate. When you are alone, you should hang it on the door frame on the right, and when you are two, you should hang it on the door frame under the eaves, which not only has the meaning of "double circle" and "boundless prosperity", but also can exorcise evil spirits and hide filth.
