Testing Angels: An Everlasting Light in the Human World

This is an epic tale of entrepreneurship spanning a century. From the famine-stricken years of 1931 in the Guanzhong region of Shaanxi to the New Year's Eve lights of a future city in 2120, six generations are linked by an old ledger inscribed with the words "Measuring the Heavens." Grandfather Chen Tiezhu is a carpenter, measuring grain and human hearts beneath an oil lamp. Father Chen Jianguo is a veteran, measuring rock strata and loyalty in tunnels. Son Chen Chuan is a geological engineer who quits his job to start a business, measuring markets and kindness with algorithms. His grandchildren return from overseas and turn "Heaven Measurer" into a technology company with a global impact. This is a story of inheritance and betrayal, ideals and reality, hardship and hope. In every era, each generation sets out to "measure the heavens": measuring the times, human nature, and the world they live in. And that ledger, begun in 1931, keeps being written all the way to 2120.
