A tourist guide injured 20 people in a slashing rampage following a quarrel with another guide while conducting a sightseeing tour around the Sifang Street in the ancient City of Lijiang, southwest China's Yunnan Province Sunday, local government authorities confirmed Monday.

Xu Minchao, a 25-year-old national tourist guide with a travel agency in northeast China's Jilin Province, lost control of his emotion after a row with Peng, a local guide with a travel agency in the capital city of Kunming, and whisked a knife to cut 20 people, mostly tourists and guides, reported China News.

Xu was caught on the spot, and the injured people, 15 of whom are tourists from other parts of the country, were rushed to hospital for treatment. Two of them were heavily injured.

Rescue work is under way, and further investigation is being carried out.
