The traditional Chinese calendar divides a year into 24 solar terms.[1] Chǔshǔ, Shosho, Cheoseo, or Xử thử (traditional Chinese: 處暑; simplified Chinese: 处暑; pinyin: chǔshǔ; Japanese: 処暑; rōmaji: shosho; Korean: 처서; romaja: cheoseo; Vietnamese: xử thử; "limit of heat") is the 14th solar term that signifies the end of the hot summer season.[2] It begins when the Sun reaches the celestial longitude of 150° and ends when it reaches the longitude of 165°. It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 150°. In the Gregorian calendar, it usually begins around 23 August and ends around 7 September.
