The World Junior Wushu Championships (WJWC) is an international wushu competition organised by the International Wushu Federation (IWUF) for competitors (both male and female) below 18 years of age.
There are two categories for the "taolu" events - under 15 and under 18 years of age.
The competition also includes a sanshou category. 
The 2007 World Wushu Championships are the 9th edition of the World Wushu Championships, and were held at Olympic Sports Center Gymnasium in Beijing, China from November 11 to November 17, 2007.
It acts as the qualifying tournament for the Wushu Tournament Beijing 2008.
Over 1400 athletes, referees and officials from 89 countries and regions in five continents gathered in Beijing to attend the Championships in which 15 countries and regions won gold medals and 30 obtained silver or bronze.
Athletes of 22 countries and regions ranked in the top 6 of 22 Wushu Taolu events (11 Men's and 11 Women's), while athletes of 21 countries and regions ranked in the top 8 of 18 Wushu Sanshou Categories (11 Men's and 7 Women's). 
The Great Britain Wushu Championships was one of the first Wushu Championships to be held in Europe in order to help promote the sport of Wushu.
This competition has been held annually for over 20 years and organised by the British Council for Chinese Martial Arts (BCCMA).
The competition has been run in accordance with International Wushu Federation (IWuF) rules and follows the same format of categories.
Chang Quan - Northern Open Hand  Nan Quan - Southern Open Hand  T'ai chi ch'uan (or Taijiquan) - Internal/Soft style Open Hand  Daoshu - Broadsword  Jianshu - Straightsword  Gunshu - Staff/Cudgel  Qiangshu - Spear  Tai Ji Jian - Taiji Sword  Nandao - Southern Style Broadsword (added in 2002)  Nangun - Southern Style Staff/Cudgel (added in 2002) These categories were divided into male and female for senior athletes (over 18 years old).
Up until 1990 the categories were listed as "optional" or "free-form" events.
Meaning the athlete may choreograph their own routines using techniques within the rules of the IWuF.
From 1990 to 2000 each category was assigned a standardized Taolu routine by which each athlete competed with.
This was to enable fair participation among all levels of competitors.
In 2000, the IWuF sanctioned a new set of standardized Taolu routines to Chang Quan, Daoshu, Jianshu, Gunshu and Qiangshu.
With an new inclusion of two Southern style weapons events Nandao and Nangun.
These new standardized routines remained in effect for senior competition until 2004 when "optional" routines were once again brought back.
Since 2004, optional routines are used for all categories at senior level competition.
The emphasis on this style of performance is to increase the level of difficulty in each routine by performing (and being strictly judged on) varying degrees of aerial and balancing techniques.
Wushu competition in Great Britain and around the world is now vastly different from the 1970s to 2000.
Before the inclusion of "nandu" (otherwise known as difficulty techniques), routines were marked on their technical and performance standard.
Today, the "nandu" is what reaps most of the score and failure to achieve the requirement results in an extremely low result.

This is again run in accordance with IWuF rules.
Each category is defined by age and has a standardized routine for the athletes to use for competition. 
Stances are a highly fundamental part of all Chinese Martial Arts.
Wushu is characterized by low, wide stances designed for mobility and protection.
Stability is another key concern of Chinese martial arts, and the wushu stances reflect this sensibility.
There are five key stances utilized in both contemporary wushu and traditional wushu.
Many others exist, and different styles of wushu prescribe a particular protocol for "correct" stance. 
Wushu at the 2005 Southeast Asian Games took place in the Emilio Aguinaldo College Gymnasium, in Ermita, Manila, Philippines.
The event was held from November 28-30.
Wushu () literally means "martial art".
It is a more precise term than the widely used term kung fu, which can mean either martial art or ""skill"": a craftsman or artisan could be said to have good "kung fu" in the way in which they carry out their craft; in the same way, a wushu practitioner can also be said to have good "kung fu" in their wushu practice.
In the broadest sense, the word wushu may refer to any martial art in the world, though in practice it often refers to all categories of Chinese martial arts, traditional, contemporary, hard and soft.
Today, the terms "modern wushu" or "contemporary wushu" refer to forms that are practised for health, exhibition and competition.
Common "hard" or external styles of contemporary wushu are southern fist, "Nanquan" and long fist, "Changquan".
Common "soft" or internal styles are Taijiquan, Baguazhang and Xingyiquan.
Wushu is practised in forms (taolu in Chinese) which comprise basic movements (stances, kicks, punches, balances, jumps and sweeps) particular to each style and can be changed for competitions to highlight one's strengths.
Competitive forms can vary in length from 1 minute, 30 seconds for the hard styles to over five minutes for internal styles.
