2. Since ancient times, bamboo has been considered as an auspicious plant. "Bamboo" and "bamboo" are homophonic, meaning good wishes. The homonym of bamboo means good luck. According to legend, firecrackers, which are essential for the Chinese New Year, were originally made of bamboo as the raw material for outer packaging. When they are lit, they make a "bang" sound, which is regarded as an exorcism to protect people's peace and happiness.
