The Chinese Gourd is popular as a charm symbol representing good health and an abundance of divine blessings because its first character (wu) has the same pronunciation as the word to 'protect' and also the word for 'blessing'. Wu Lou's shape is believed to be a representation of Heaven and Earth united in miniature.
The shape of a Wu Lou looks like the auspicious figure 8 which is widely regarded as a universally lucky number signifying endless or continuous prosperity.
Wearing a Wu Lou pendant enhances one's Feng Shui. Carved with prosperity symbols and wealth luck, it dangles a petite pearl bead and "Fatt" (prosperity).
