Which two practices did Zen Buddhism encourage people to cultivate in China during the middle ages

Meditation and self-control.

Explanation:

Zen is a practical method of realizing Buddha nature. This means that it is an attitude of life that permeates all of our actions. In Zen we develop mindfulness through a discipline of body and mind, experienced in a simple and direct way in the here-now. It is worth mentioning that Zen Buddhism is a religious tradition with its own philosophical principles and that, like many other traditions, it has several Ceremonies and Liturgies. In China Zen influenced people to cultivate the habit of meditation and self-control. These concepts are still cultivated today, not only in China, but in different parts of the world.

Two practices Zen Buddhism encouraged people to cultivate in China during the Middle Ages include meditation (to still and balance the mind) and self control (controlling one's thoughts, emotions, and behaviors).
