If you are after good luck and believe in avoiding disaster, then you need to open your mouth to remove seeds. It is said that gourd can turn disease into qi and effectively restore the two black disease symbols. People who are sick all the year round can be placed at the bedside or at home, which is beneficial to the health of their families.
In addition, gourd also has the homonym of Fulu, and folks also have the practice of increasing luck.
If you believe in the latter, then open the light for the gourd, and it will be better to soften the suffocation with a cork after opening the light.
