A long-awaited heavy rain is moistening the dry and thirsty red earth beneath his feet. Patrick Nijs couldn't hold back his joy."I feel that my land and crops are very happy," he says. Those thirsty corn sprouts have had their share of "drinking" at last.

Just three weeks ago, Nijs insisted on planting 150 eggplant seedlings despite opposition from a trusted friend. However, they almost got completely wiped out due to drought. This compelled him to appreciate more the wisdom of Chinese farmers, and especially take note of the 24 divisions of the solar year in the traditional Chinese calendar.

Nijs, 70, is a former Belgian ambassador to China, a lifetime honorary ambassador, and co-founder of the EU-China Joint Innovation Center. Seven years ago, he gave up the opportunity to go to Turkey to continue his diplomatic career, and returned to his wife Deng Minyan's home area, a copper-depleted city called Dongchuan in Southwest China's Yunnan province. The city is known as the "World Mudslide Natural Museum". In the vast mountains and plateaus, the couple started to explore sustainable agriculture, and live a quiet life of sunrise and sunset.

Nijs now spends all his time in the field sowing, weeding, composting, watering and picking.

Occasionally, he also chats with friends in the village. Farmer Li Guanghe, 68, is his best friend in the village, and they often farm together, eat, drink, and even smoke cigars together. But sometimes, the two can be at loggerheads on matters agricultural.
