World Exposition Knows (Two): Rules Of City Election In Host Countries Of World Expo

According to the election rules, each member of the International Exhibition Office has the right to vote for one vote regardless of size. In the first round of voting, if a candidate city gets more than 2/3 of the vote, the city will become the host city of the world exposition. If there is no candidate city in the first round of polling, the second round of voting will take place, but those who have the least votes in the first round of voting will no longer compete. In the second round of voting, candidate cities with more than 2/3 votes were elected. If there is still no more than 2/3 of the votes of the city, the third round of voting will continue according to the above way until the 2 cities with the largest number of votes are elected. The final competition will be carried out by these 2 cities, among which more votes are given.
