Uniting brings advantages, division brings disadvantages

Unity is strength

One chopstick is lightly broken, but ten chopsticks are tightly held together (song)

With people united, Mount Tai can move

It’s hard to walk with one foot, and it’s hard to sing with a single hand

A rising tide lifts all boats, and more firewood makes the fire prosper

Three cobblers, Better than Zhuge Liang

A brick cannot build a wall, and a piece of wood cannot build a house

Example: In the context of economic globalization, for example, cars produced in Japan, tires are from Korea, and electronic appliances are from Korea. It's from Japan, the small parts are from China, and the fuel-saving system is from Japan. Cooperation is conducive to "mutual help, complementarity and win-win".
