Lubansuo, also known as Kongmingsuo, all the solutions are as follows: first, take out the weighbridge 1 and the front eaves No.2 and insert them into a cross.

Secondly, carefully look at the cross splicing method of 1 weighbridge and No.2 front eaves, assemble the Luban lock cross structure, and then find out No.3 right column for assembly.

Thirdly, assemble the No.3 right column into a cross-shaped three-dimensional structure, and take out the No.4 left column for assembly.

Finally, install the No.4 left column at the position opposite to the No.3 right column, then take out the rear eaves for assembly, install the No.5 rear eaves in turn, and then rotate the No.4 left column to prepare for the assembly of the top beam. There is also the need to install the No.6 roof beam and rotate the No.4 left column.
