These characters combine literally and directly to mean “according to the model, draw a gourd.” This literal action serves as a metaphor for any situation where someone follows a pre-existing pattern or example without deviation or thought.
The idiom `依样画葫芦` originates from a story set in the Song Dynasty. A scholar-official named Tao Gu noted that the imperial academy painters of his time had lost their creativity. When they were asked to paint a specific scene, they would simply find an old master's painting of a similar subject and copy it. Tao Gu lamented this practice, comparing it to “drawing a gourd based on an existing model.” This story highlights a deep cultural tension in China. On one hand, Chinese tradition places immense value on learning from masters, which often begins with meticulous imitation. On the other hand, true mastery requires moving beyond imitation to develop one's own style and understanding. `依样画葫芦` criticizes the failure to make this leap. It's the point where respect for a model turns into a crutch that prevents growth.
This chengyu is widely used in various contexts, almost always with a negative connotation.
