Yo-yo

A yo-yo (also spelled yoyo) is a toy which in its simplest form is an object consisting of an axle connected to two disks, and a length of string looped around the axle, similar to a slender spool. It is played by holding the free end of the string known as the handle (usually by inserting one finger in a slip knot) allowing gravity or the force of a throw to spin the yo-yo and unwind the string (similar to how a pullstring works), then allowing the yo-yo to wind itself back to one's hand, exploiting its spin (and the associated rotational energy). This is often called "yo-yoing". First made popular in the 1920s, yo-yoing remains a popular pastime of many generations and cultures. It was first invented in ancient Greece.

In the simplest play, the string is intended to be wound on the spool by hand; The yo-yo is thrown downwards, hits the end of the string, then winds up the string toward the hand, and finally the yo-yo is grabbed, ready to be thrown again. One of the most basic tricks is called the sleeper, where the yo-yo spins at the end of the string for a noticeable amount of time before returning to the hand.

Columns (juggling)

In toss juggling, columns, also known as One-up Two-up, is a juggling trick or pattern where the balls are thrown upwards without any sideways motion. The simplest version involves having three balls, with two going up simultaneously on either side, followed by one going up in the middle. One way to accomplish this is to juggle 2 balls in one hand and one ball in the other, so one hand has to move faster and further than in a regular pattern (cascade), whilst the other remains almost stationary. The hand juggling the center ball can alternate with each repeat to make the pattern symmetric.

Variations

There are many variations to this simple three-ball pattern. Some involve alternating the placement of the 'lone' inside throw, while others involve the two outside throws.

The 'lone' ball may be to either side of the two balls, and can have its position in relation to them altered whilst juggling the pattern by throwing it not at a vertical angle, or moving the hand holding it when it has been caught. This ball can also be thrown quickly from one hand to the other as in a box pattern, whilst the other two balls are in midair.

Nanjing

Nanjing ( listen; Chinese: 南京, "Southern Capital") is the city situated in the heartland of drainage area of lower reaches of Yangtze River in China, which has long been a major centre of culture, education, research, politics, economy, transport networks and tourism. It is the capital city of Jiangsu province and the second largest city in East China, with a total population of 8,216,100 and legally the capital of Republic of China which lost the mainland during the civil war. The city whose name means "Southern Capital" has a prominent place in Chinese history and culture, having served as the capitals of various Chinese dynasties, kingdoms and republican governments dating from the 3rd century CE to 1949. Prior to the advent of pinyin romanization, Nanjing's city name was spelled as Nanking or Nankin. Nanjing has a number of other names, and some historical names are now used as names of districts of the city, and among them there is the name Jiangning (江寧), whose former character Jiang (江, River) is the former part of the name Jiangsu and latter character Ning (寧, simplified form 宁, Peace) is the short name of Nanjing. When being the capital of a state, for instance, ROC, Jing (京) is adopted as the abbreviation of Nanjing. Although as a city located in southern part of China becoming Chinese national capital as early as in Jin dynasty, the name Nanjing was designated to the city in Ming dynasty, about a thousand years later. Nanjing is particularly known as Jinling (金陵, literally meaning Gold Mountain) and the old name has been used since the Warring States Period in Zhou Dynasty.

Nanjing (Liao dynasty)

Nanjing was the name for Beijing during the Liao dynasty, when Khitan rulers made the city the southern capital. To distinguish Nanjing, which literally means "South Capital" in Chinese, from modern Nanjing in Jiangsu Province, Chinese historians sometimes refer to Beijing during the Liao dynasty as Liao Nanjing (simplified Chinese: 辽南京; traditional Chinese: 遼南京; pinyin: Liáo Nánjīng). The Khitan rulers of the Liao acquired the city, then known as Youzhou, in the cession of the Sixteen Prefectures in 938 from the Later Jin, and the city was officially renamed Nanjing, Youdu Fu (南京幽都府). In 1012, the city was renamed Nanjing, Xijin Fu (南京析津府). The city was also colloquially referred to at the time as Yanjing. In 1122, the city was captured by the Jurchen Jin dynasty and was officially renamed Yanjing, ending the use of Nanjing for what is today modern Beijing.

Location and orientation

Liao Nanjing is located in the southwestern portion of modern Beijing, in the southern half of Xicheng District (formerly Xuanwu District).
