Richard from Guangzhou (South China) sent me this view of Jigong Hill at Xinyang.

Postcard sent by Kuang with the view the Black Dragon Pool in Yuquan Park (Jade Spring Park), China.

The Black Dragon Pool is a famous pond in the scenic Jade Spring Park (Yu Quan Gong Yuan) located at the foot of Elephant Hill, a short walk north of the Old Town of Lijiang in Yunnan province, China. It was built in 1737 during the Qing Dynasty and offers a spectacular view on the region's tallest mountain, Jade Dragon Snow Mountain, over its white marble bridge. The park features several smaller temples and pavilions:
* The Moon-Embracing Pavilion, which was originally built in the late Ming Dynasty. The current structure is a reproduction from 1963 after a fire in 1950.
* The Dragon God Temple (Longshen Temple) was constructed by local Naxi people in 1737 and is located to the east of the park. It was given the name Dragon God of Jade Spring by Emperor Qianlong of the Qing Dynasty in the same year.
* The threefold overlap Five-Phoenix Tower (Wufeng Tower) was built during the Ming Dynasty (1601), and today located at the north end of the park. The tower was originally situated at the Fuguo Temple, which is 30 kilometers to the west, but was moved to Jade Spring Park in 1979.
The park is further home to the Dongba Culture Research Institute and the Dongba Culture Museum.

The Great Wall of China is fantastic. Sent by Alex.

The Great Wall of China is a series of stone and earthen fortifications in northern China, built originally to protect the northern borders of the Chinese Empire against intrusions by various nomadic groups. Several walls have been built since the 5th century BC that are referred to collectively as the Great Wall, which has been rebuilt and maintained from the 5th century BC through the 16th century. One of the most famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains; the majority of the existing wall was built during the Ming Dynasty.
The Great Wall stretches from Shanhaiguan in the east, to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia. The most comprehensive archaeological survey, using advanced technologies, has concluded that the entire Great Wall, with all of its branches, stretches for 8,851.8 km (5,500.3 mi). This is made up of 6,259.6 km (3,889.5 mi) sections of actual wall, 359.7 km (223.5 mi) of trenches and 2,232.5 km (1,387.2 mi) of natural defensive barriers such as hills and rivers.

The card from Li Tong, a 20 years old Chinese girl. It depicts the Yulong (Jade Dragon) Snow Mountain & the ancient city of Lijiang, China.

Wiki says:
Jade Dragon Snow Mountain is a mountain massif (also identified as a small mountain range) near Lijiang, in Yunnan province of southwestern China. Its highest peak is named Shanzidou (5,596 m or 18,360 ft). The view of the massif from the gardens at the Black Dragon Pool (Heilong Tan) in Lijiang is noted as one of China's finest views. The far side of the mountain forms one side of Tiger Leaping Gorge (Hutiao Xia).
Shanzidou has been climbed only once, on May 8, 1987, by an American expedition. The summit team comprised Phil Peralta-Ramos and Eric Perlman. They climbed snow gullies and limestone headwalls, and encountered high avalanche danger and sparse opportunities for protection. They rated the maximum technical difficulty of the rock at YDS 5.7.
The Austro-American botanist and explorer Joseph Rock spent many years living in the vicinity of Jade Dragon Mountain, and wrote about the region and the Nakhi people who occupy it. An interest in Rock later drew the travel writer Bruce Chatwin to the mountain, which he wrote about in an article that appeared in the New York Times and later, retitled, in his essay collection What Am I Doing Here?. Chatwin's article inspired many subsequent travellers, including Michael Palin, to visit the region.
The Jade Water Village is at the foot of the mountain.

With Postcrossing the world seems closer to me, but at the same time more unknown and, therefore, more interesting.
