A small amount of gold can achieve the effect of making the main body entirely out of gold. Gold leaf application technology is widely used in antique architecture, modern buildings, golden plaques, and more, such as gold leaf application on Buddha statues, painted beams and carved rafters, and decorative gold leafing. The most famous gold-leafed structures include: Beijing's Tiananmen Square, the Great Hall of the People, China Central Television Headquarters, Shanghai's Oriental Pearl Tower, and Tibet's Potala Palace. Additionally, gold leaf is also a raw material for producing high-quality ink for painting. With the liberalization of the gold market and the improvement in people's living standards, the application scope of gold leaf is bound to become even broader. In summary, the uses of gold leaf are extensive, spanning various fields such as Buddhism, classical gardens, high-end architecture, healthcare, and cultural endeavors. Among these, gold leaf application on Buddha statues, painted beams and carved rafters, plaques and couplets, and decorative purposes are the most common applications. Various foil products are now widely used worldwide. Gold leaf, copper leaf, and aluminum leaf are extensively applied in European parliaments, opera houses, churches, mosque domes, and numerous museums and palaces. From China's Tiananmen Square, the Summer Palace, the Forbidden City in Beijing, the Shaolin Temple, the Confucius Temple in Shandong, the Potala Palace, Nanjing's Qixia Temple, and Suzhou's Hanshan Temple, to more distant landmarks such as the Moscow China Hotel, the Thai Royal Palace, the Osaka Gate in Japan, the presidential residence of Zaire, and St. Petersburg—the shimmering gold leaf on these world-famous structures often comes from Dongguan.
