Chinese Football League (CFL) Round 4 is a round-robin tournament that features all the top clubs from China's professional football league system. It was originally introduced as part of the Chinese Super League in 2017, but has since been expanded to include all the major clubs in the country.

In this format, each club plays every other club exactly once, resulting in a series of head-to-head matches. This means that no single team can claim victory or defeat in a match, and it creates a high level of excitement and tension among fans.

The format of round 4 is dynamic and unpredictable, with the outcome of each match affecting the next one. This makes it a highly competitive tournament that requires exceptional skills and performance from players at every position on the pitch.

Each match is a test of the team's fitness, determination, and resilience, and it is crucial for determining the progress of the league. Players who perform well in rounds 1-3 can expect to be promoted to round 4, while those who struggle may find themselves relegated to the lower divisions.

The round 4 fixtures are released ahead of the season, so fans can plan their schedules accordingly. The tournament is also a great opportunity for fans to support their favorite teams, as they can watch them compete in front of their home crowds.

Overall, round 4 of the Chinese Premier League is a highly anticipated event that showcases the best talent in China's football league system. Fans around the world look forward to watching the exciting matches and supporting their favorite teams throughout the season.
