Problem: Zhejiang:

Zhejiang is mountainous and has therefore fostered the development of many distinct local cultures. Linguistically speaking, Zhejiang is extremely diverse. Most inhabitants of Zhejiang speak Wu, but the Wu dialects are very diverse, especially in the south, where one valley may speak a dialect completely unintelligible to the next valley a few kilometers away. Other varieties of Chinese are spoken as well, mostly along the borders; Mandarin and Huizhou dialects are spoken on the border with Anhui, while Min dialects are spoken on the border with Fujian. (See Hangzhou dialect, Shaoxing dialect, Ningbo dialect, Wenzhou dialect, Taizhou dialect, Jinhua dialect, and Quzhou dialect for more information).

Question: The possibility of unlikely victories in the earlier rounds of the competition, where lower ranked teams beat higher placed opposition, known as "giant killings", is much anticipated by the public, and is considered an integral part of the tradition and prestige of the competition, alongside that gained by teams winning the competition.

It is considered particularly newsworthy when a top Premier League team suffers an upset defeat, or where the giant-killer is a non-league club, i.e. from outside the professional levels of The Football League.
