Davis Cup is the "World League" of tennis men's team, which adopts the single defeat elimination system. Davis Cup is similar to a pyramid, with 16 teams participating in the world group at the top, followed by the first group in America, the first group in Asia-Pacific, the first group in Europe and Africa, and the second, third and fourth groups in America, Asia-Pacific and Europe and Africa at the top respectively.
Among them, the winning team in the fourth group will be promoted to the third group next year, and the third group will not only produce the team that will be promoted to the second group next year, but also the team that ranks last will be reduced to the fourth group. By analogy, in the second year, eight teams participated in the world group qualifiers, of which the first group of America and Asia-Pacific each had two qualifying places, and the first group of Europe and Africa had four qualifying opportunities.
Last year, the eight teams that qualified in each district will compete with the eight teams that lost in the first round of the world group competition for the qualification to participate in the world group competition next year. The eight teams that won the first round of the World Group not only retain the qualification to participate in the World Group competition next year, but also have the opportunity to compete for the final championship.
Davis Cup Tennis Tournament is an annual world men's team tennis tournament, and it is also the highest level and most influential international team tennis tournament in the world. Sponsored by the International Tennis Federation, it is the longest tennis match except the Olympic Games. Because it was sponsored by American Davis and donated a silver cup to the champion team, it was named "Davis Cup Tennis Tournament". 1 on 1900 was held in Boston, USA. Only the United States and Britain participated. Davis himself is the captain and athlete of the American team, and led the American team to win the trophy by defeating the British team 3-0 in that year's competition. Due to the increase of participating countries, 1923 is divided into America and Europe, and the two regions are divided into regional preliminaries and then finals. 198 1 Two-level competition is adopted. 1952 Due to the increase of the team, in addition to the original American area and European area, an Oriental area was added, which was divided into three areas for the preliminary competition, and then the second champion team was produced and the last champion team was challenged. 1966 The number of European teams increased dramatically, and it was divided into four regions from three regions, namely, America, Oriental, Europe A and Europe B (African countries participated in Europe B). 1970 set up a Committee to study and discuss the reform of competition rules. Many countries think that it is unfair for defending countries to wait for the opportunity to face the exhausted challenge team, so they passed a resolution in 197 1 to cancel the "challenge" system. Starting from 1972, the champion team must start the competition from the first round without exception. This change will never happen again, because the United States and Australia have monopolized this laurel year after year.
With the increase of competition history, the original competition system has not adapted to the new situation, so the rules of Davis Cup competition have changed accordingly. 1 July, 1980 and 1 July, 1988 revised the rules twice, and changed the original oriental region into Asia-Pacific region, which was divided into Asia-Pacific1group and Asia-Pacific 2 group, with1group having the highest level. 1 group, one team in the upper and lower half. The original Europe A and Europe B were changed to Europe-Africa 1 group, and they were still divided into region A and region B, and the top two in each region obtained the qualification of world group. Two groups in Africa and two groups in Europe were added. The level of the second group in each district is lower in this district. In this way, two teams from Asia-Pacific 1 Group, America 1 Group and Europe-Africa 1 Group A and B entered the world group qualifiers respectively, and drew lots with eight teams eliminated in the first round of World Group 16 that year, and the winner rose to the second place.
The Davis Cup competition system is to draw lots to decide the home team and the visiting team, and the home team has the right to choose the venue and venue type. Every game between the two teams adopts the best of five games system, playing five games. I played two singles on the first day, a doubles game on the second day and two singles games on the third day. The competition adopts the best of five games system. After the game is decided, the best of three sets can be adopted.

The two groups used a home game and an away game respectively. In the world group, the four teams that won in the first round played semi-finals, the four teams that failed in the first round played against the four teams that won in Group A, and the winning team entered the world group at the end of next year. The team that failed in the first round of Group A will compete with the winning teams in each district, and then the four winning teams will enter the Group A competition next year. Four failed teams will take part in next year's district-level competition. Among them, the World Group and Group A adopt the best of five games, with two singles on the first day and two singles and one doubles on the second day. Its doubles match was held at the end.

Generally, the highest level World Team 1/4 final is held in April (China will participate in this competition in 2007), and the other teams will hold regional qualifiers to decide whether they will be promoted or demoted (in April 2006, China took part in the World Group A final and beat Indonesia to advance to the World Group Play-offs), and then the World Group Play-offs (teams will be promoted) will be held in mid-July. Then in September, the highest-level world group final will be held (if China can beat her opponent in the world group in April and July next year, she can compete for the world-class women's tennis team championship).
