This collection of postal history on Christian mission began on a Sunday morning when a Dr James Hudson Taylor III came to preach in Chin's church. Dr Taylor is the great grandson of the late Dr J. Hudson Taylor (1832-1905), founder of China Inland Mission which pioneered Christian work in the interior of China. Chin saw the potential to start a historical philatelic collection. Her effort to consolidate all her hours of hobby and study is now presented in this book.
