投入

投入 refers to an investment of time, effort, or resources into something with the expectation of gaining a benefit or result. It emphasizes dedication and commitment rather than mere participation.

The character 投 (tóu) originally meant 'to throw' or 'to cast,' while 入 (rù) means 'to enter' or 'to go in.' Together, they suggest 'casting something into a direction or purpose,' which metaphorically represents investing energy or resources into a goal.

投入 is commonly used in contexts such as business, education, and personal development. For example, people might talk about 投入 time into learning a skill or 投入 money into a project. It reflects the cultural value placed on hard work and long-term planning in Chinese society.
