Since he turned 70, Li Xiaoke has emphasized the variations of lines in his paintings. These days, he explores the thickness of ink more. He utilizes the possibilities of monochromatic color to depict, for example, the solidity of architecture, the width of trees or the softness of temples' curtains flying in the wind.

"With a brush, ink and water, he displays Chinese brushwork well, turning sophistication into simplicity and uses simplicity to reflect sophistication," Liu says.

Even when he needs to add other colors, Li Xiaoke only adds them to the people in his paintings, the blossoms and the sky.

Li Xiaoke says painting is not just about skills or personality, it is about every stroke an artist makes with a peaceful heart and mind. He says it is like farming, where one reaps what one sows.

"Only when people are down to earth, and put themselves in a humble position, can they gain an objective view of the world."
