Thematic significance
"Building blocks" have a strong symbolic significance. Almost everyone played the game of "building blocks" when he was a child, and the houses should be built the most. Building blocks skillfully connects "building blocks" with "home", which naturally causes people's various memories and associations, and its significance has also become much richer. The song that "he" and "she" sang when they were in love was:
"Building blocks, we are together, red and green, beautiful, what to build, houses, small doors and windows, sharp tops. Holding hands and not talking, we walked into the house. "
It can be seen that people have a hazy yearning and mysterious yearning for "home" since childhood. However, once there is a crisis, the "home" built by "building blocks" becomes crumbling. Just as "He" said, "Just a few building blocks will collapse if you don't push them", which completely exposed the fragility and instability of "home" and mocked his naive fantasy about "building blocks".
When "she" asked "he" to make a change, "he" said, "Everything is fixed, just like building blocks. If it is changed, it can't be inserted." This is not only a kind of self-mockery, but also adds a little helplessness. Here, "building block" is not only synonymous with the construction and collapse of "home", but also a symbol that it is not free and difficult to stretch under the established social order and code of conduct.
