Huang Xing is an author about whom limited public information is available; the library currently holds two of his works, spanning the notably different fields of inspirational personal growth and programming design. His representative work Dayi (Great Righteousness) belongs to the inspirational growth category and, judging from its title and classification, likely explores morality, responsibility, and life choices for readers seeking motivation and reflection on values. Microservices in Practice (Dubbox + Spring Boot + Docker) belongs to the programming design category; its title indicates a focus on microservice architecture involving specific technical tools such as Dubbox, Spring Boot, and Docker, aimed at developers with some foundation and strongly oriented toward hands-on practice. Since no reliable records exist for his dates of birth and death, nationality, or educational background, this introduction makes no speculation and offers only an objective account of the subject matter of the available works for readers' reference.
