On the annual Dragon Boat Festival, it's customary to send zongzi to loved ones. However, there are taboos associated with this practice. A fortune-teller warned against sending zongzi 'strung together,' as one person's negligence in this regard led to tragedies within the family. Apart from this taboo, it's believed that zongzi with lye should not be given within a year of a family member's passing. Experts advise following these customs to avoid misfortune.
