The ability of Zhang Qing Garden to grow vegetables is still very strong. When he was young, he had mastered certain vegetable planting skills. He can grow beautiful peppers, carrots and vegetables, all of which are high-quality products. So in modern times, he is half an agricultural expert. Moreover, with the technology of growing vegetables, you don't have to worry about eating and drinking water anywhere. When he brings this technology to others, he can bring wealth to others and income to himself. Zhang Qing's ability to grow vegetables is superb, so when he was in Mengzhou, Guangming Temple asked him to be the head of the vegetable garden. Although we see that Zhang Qing is only the owner of a vegetable garden, we should know that all the food eaten by monks in the temple comes from this vegetable garden, so it is a good position to be the person in charge of the vegetable garden in the monk temple. Besides, all the vegetables in the garden need watering and fertilization. As long as Zhang Qing earns some kickbacks on some small links of this vegetable, there is still a lot of oil and water. But later, just because Zhang Qing's little wishful thinking in the garden was discovered by the monks, Zhang Qing killed the monks and burned the temple. Finally, he went to his wife and opened a small restaurant.
Therefore, I think Zhang Qing's vegetable growing skills in the garden are not detailed in Water Margin, but his vegetable growing skills are still superb. Otherwise, there would be no special temple to invite him to be the director of the vegetable garden. In addition, Zhang Qing is a witty person, and his mind is very clever, which is also needed for growing vegetables.
