1。 First of all, according to the literal meaning, it can be concluded that Li and Zhao are not from Shanghai, Chen is not from Guangdong and Lin is not from Fujian.
2。 Since 5, Zhao Xin's speed skater has only competed with one athlete, so according to 4, Zhao Xin is not from Guangdong, Fujian or Beijing, so Zhao Xin is from Hubei.
3。 Chen is from Shanghai because he has fought against Cantonese, but not Fujian and Hubei.
4。 This is a crucial step. Chen played with three other people, and he only played with Cantonese. Li must be one of Guangdong, Fujian and Beijing, and he has only played twice, that is, only with two other people in Guangdong, Fujian and Beijing. So Li is from Guangdong.
5。 Because no one else is from Fujian, Zhang Zhang is from Fujian.
6。 It turns out that Zhao is from Beijing.
It's easy to do it with a table.
