As the owner of Tianfuyuan Ecological Farm, Zhang Zhimin used to be a diplomat and international business engineer who only engaged in mental work. Twenty years ago, because of a serious illness, she began to engage in agriculture. Adhering to the agricultural philosophy of "respecting and cooperating with nature", she has gradually turned her farm into the only ecological diversity farm in Beijing. At a time when the relationship between man and nature is becoming increasingly tense, Tianfuyuan Ecological Diversity Farm has embarked on a new agricultural road.
