Luo Guo-jhang often paints animals as the theme of his creations. According to his own imagination, he paints animals through repeated and careful color mixing, so that the animals in his paintings always have simple and vivid expressions. Animals are also used by Guo-jhang to symbolize social relationships. He records the society he sees through the animals, which is a harmonious and peaceful world. The animals in the works are all happy. They are either having a party, playing hide-and-seek, or enjoying family happiness. For Guo-jhang, these are his daily feelings, and he hopes that everyone can feel mental healing and be inspired by his works.
