When you encounter this problem, you should look at the drawings carefully, identify the building blocks and colors, pay attention to the arrows and lines, and step by step.

1. Read the drawing instructions carefully: read the drawing instructions carefully before starting.

2. Identify the building blocks and colors: classify the building blocks according to colors and mark them according to the colors on the drawings, so as to find the required building blocks more easily in the assembly process.

3. Pay attention to arrows and lines: arrows are usually used to indicate the association and assembly direction of building blocks in drawings, and lines are used to distinguish different building blocks.

Step by step: don't try to finish all the work at once. Break the drawing down into several steps, one by one.
