The Chinese characters “暑函” are pronounced as “shǔ hán”. In English pronunciation, “shǔ” can be approximated as “shoo”. “hán” can be pronounced like “hahn”. When we combine these two pronunciations, we can say something like “shoo hahn”. It's important to note that this is just an approximation as English doesn't have exactly the same sounds as Chinese. The pronunciation might vary slightly depending on different accents and speakers. ????
