1. The plum blossom lock has three columns. After the three columns are arranged according to the figure, the position length from the center to each side is equal, and there will be six vacancy directions. These spaces are used to install petal blocks.

2. The order of petal blocks can be found regularly. Usually the installation sequence is down, back, lock, front, left and right. In this order, the plum blossom lock can be successfully restored.

3. After the lower petal block is installed, we find the rear position and then install the petal block. It's important to find the relative position. Each petal is outward.

4. Among the six petals, one has a thin middle position, which is the "lock" of the plum blossom lock. This block needs to be placed in the upper position, and it should be placed horizontally first.

5. Next, we will restore the petal block in front.

6. There are two petals left, left and right. When installing the left and right blocks, we need to lift the "lock" block first, and then open the left and right blocks separately, so that the plum blossom lock can be basically restored.

7. In the last step, we need to turn the "lock" of the plum blossom lock upward to successfully restore the plum blossom lock!
