Beijing China
2014

Beijing, China’s sprawling capital, has history stretching back 3 millennia. Yet it’s known as much for modern architecture as its ancient sites such as the grand Forbidden City complex, the imperial palace during the Ming and Qing dynasties. Nearby, the massive Tiananmen Square pedestrian plaza is the site of Mao Zedong’s mausoleum and the National Museum of China, displaying a vast collection of cultural relics.

The yin yang symbol is often referred to as "taijitu" in China. It's a familiar symbol you've likely seen many times on jewelry, clothes, notebooks, etc. There are many variants of the symbol, but the most common is a circle composed of two interlocking swirls/teardrops, one black and one white. Each swirl has a dot of the opposite color in it.

The yin yang symbol represents the interconnectedness of the world, particularly the natural world. There can be no positive without a negative, no open without closed, no light without shadow. The yin yang symbol itself portrays that interrelatedness.
Looking at the symbol, you can see it doesn't have a straight line going through the center to represent the divide between yin and yang. Inside, the dividing line is a soft S-shape. It shows how yin and yang are connected and constantly flowing into and out of each other. At the top of the symbol, as yang swells, yin contracts. At the bottom, yin swells as yang contracts. The ideal situation is when there is an equal balance between the two, as that is when harmony is achieved.

Within the symbol, not only do the white and black segments fit perfectly with each other to form a circle, each has a small circle of the other color within it to further show the connection between the two. The small circles also show that nothing is absolute. In all yin, there is a little yang, and vice versa. This further demonstrates the connection between the two.

The outer circle of the yin yang symbol represents the entirety of the universe. It shows that yin and yang represent everything that we know, as well as things we don't understand.
