Appreciating the painting "Father" Seeing this painting makes every reader's image full of this simple farmer, which makes me feel grateful. This may be the author's silent gratitude to his father and the land he cultivated all the year round. The painter used strong oil paints and ultra-realistic techniques in modern western art, skillfully adopted close-up composition, subtle and delicate brushwork, and drips of sweat oozing from pores on his face, creating a picture of his father with sincere feelings and simplicity.
