Dr. Philip Teng, former President of the C&MA Hong Kong Church Union and professor at Alliance Theological Seminary stated: "Chinese culture and customs form an interesting background for these exciting and intriguing stories. Powerful Christian truths lead these four young people into some life-changing situations. These are stories with a purpose."
