This book is the history and diaries of a real person. A Chinese intelligence officer named Sin Tin Hwa, sent to the USSR back in the distant seventies. A native of the city of Qingdau, in China. Who spent nine long years in a Soviet prison. And in the late eighties, fulfilling the "mission of huaqiao", he became a Christian, got married, stayed in Ukraine and lived here for a long time. The story of his life is a life at the limit of human volitional efforts, full of tragedy, love and Christian mysticism. His diaries are two kinds of notes: spiritual and psychological. Which are written through the prism of Chinese culture and Chinese consciousness. The book will be of interest to Christians of all denominations, as well as to all compatriots of Sin Tin Hwa, who with heroic tenacity carry their cross "huaqiao" outside Greater China.
