春季 (chūnjì) refers specifically to spring, while 四季 (sìjì) encompasses all four seasons.

Imagine a calendar with four distinct sections, each representing a season. The character 四 (four) looks like a box with four corners, reminding you of the four seasons, while 季 (jì) resembles a tree's leaves, which change with the seasons.

Be mindful that when discussing seasons, the context can dictate whether you use the term in a formal or informal setting. Common phrases include '四季如春' (the four seasons are like spring), emphasizing the idea of a pleasant climate year-round. Avoid mixing up seasonal terms when describing activities specific to each season.

While 四季 is not explicitly listed in the HSK vocabulary, understanding it can enhance comprehension of seasonal-related topics in HSK Level 3 and above. Focus on the individual seasons to build a broader vocabulary around weather and related activities.

In Chinese culture, the concept of 四季 is deeply intertwined with agricultural practices, traditional festivals, and poetry. Each season is celebrated with specific customs, such as the Spring Festival in spring and the Mid-Autumn Festival in autumn.

Learners often confuse the term 四季 with seasonal adjectives like 春天 (spring) or 夏天 (summer). Ensure you use 四季 when referring to the concept of all four seasons together, not just one.
