While preparing for the Chinese New Year, it’s customary to get a haircut and put away all the knives and scissors in your home during the Spring Festival celebrations so that you won’t cut into your luck for the coming year.
From a feng shui perspective, any sharp instrument or weapon represents ‘sha ch’i’ energy. Sha ch’i contributes to arguments and disputes and is counterproductive to a peaceful, harmonious environment. Despite their usefulness, you might consider keeping sharp objects out of site for the rest of the year too!
