The famous aphorisms related to shoulders are as follows:

1. Lenin: One should have his own head on his shoulders.

2. Newton: If I can see further than others, it is because I stand on the shoulders of giants.

3. Li Dazhao: He has an iron shoulder to bear moral responsibility and a tough hand to write articles.

4. Hua Luogeng: I think that people have two shoulders, which should play a role at the same time. I want to use one shoulder to carry the burden of door-to-door delivery, and deliver scientific knowledge and scientific tools to the hands of master workers. The other shoulder can be used as a ladder for young people to climb to a higher level of science.
