1. Preparation before assembly: Lego blocks come in different sizes and shapes, which will be lost if you are not careful. Before assembly, make sure that the desktop is wide and tidy, so as to avoid the loss of parts caused by excessive sundries around it and facilitate pressing. A large desktop can also be used to place assembled product parts.

2. Description, preparation of parts bags and storage boxes: Lego parts bags are labeled, so you can put them aside in order according to the instructions for easy access. Remember, only one part package can be disassembled at a time. The storage box is convenient for finding parts and reducing assembly time.

3. Classification of building blocks: There are many identical building blocks in Lego parts. After unpacking the parts package, you may wish to classify each building block and put it in the storage box. When you need to pick up parts, go to this storage box to pick up the corresponding parts, which can reduce the time of finding parts.

4. Symmetrical splicing skills: Lego bricks have many symmetrical structures. It's best to assemble these symmetrical models at the same time for some old stitching experts. This can avoid wasting time and energy in reconstruction and reduce the decline of playability caused by visual fatigue.

5, pressing skills: Lego bricks are made of plastic, although elastic, but long-term use of brute force or wrong pressing angle will also cause finger pain. Vertical compaction is usually the recommended method. Of course, don't worry if you find it difficult to buckle during the splicing process. Try changing the angle or replacing it with other same particles. For some bar-shaped building blocks, it is suggested to tilt at a certain angle to leave a certain space for the bar-shaped building blocks for convenient fastening.

6. Assembly in stages: Many Lego fans like to complete assembly at one time, but the most scientific method is assembly in stages. It takes time to spell out a complete Lego box, especially a big box. Even some professional players have to assemble 10 hours or more. For ordinary players and Lego novices, assembling in batches according to the number of parts packages not only reduces the difficulty of assembly, but also avoids the visual fatigue caused by repeated assembly.
