What is the difference between doomed love and Zhengyuan?

doomed love and zhengyuan are Buddhist concepts, which refer to unfortunate experiences and auspicious experiences in life respectively. "doomed love" refers to the adversity in life, which may be caused by social, family and other factors, or by bad things done before life, while "positive fate" is a happy experience in life, which may be obtained by combining hard work and good luck. Therefore, "doomed love" and "positive fate" represent two aspects of life, among which "positive fate" is what people look forward to and strive for most.
