Recently, the World Health Organization issued a handwritten reply to Wuhan middle school students, four pages of paper, all in Chinese, one stroke at a time. The letter's signature is "Golly Uncle", which is a transliterated Chinese name of Gauden Galea, the representative of the World Health Organization in China. Uncle Gao Li said that responding to this epidemic is a challenge for each of us, but it shows us more aspects of the Chinese, including tenacity, love and helpfulness.
