From November 28 to 30, 2025, Hua Chenyu's Mars Concert will be held at Hainan Changying Fantasy Park. To ensure smooth traffic flow and alleviate congestion around Changying South Road, Haikou has introduced 10 free bus routes to facilitate public transportation for concertgoers.

Eight free bus lines will operate from key locations, including Longhua Terminal, Haikou East Railway Station, Baishamen Bus Station, Donghe Bus Station, Hainan Institute of Industry and Commerce, Yebo Bus Station, Xiuying Railway Station, and Xingmao Shopping Center. A total of 224 buses will be deployed, allowing attendees to travel directly to the venue. Return trips will depart from designated parking areas after the concert.

Additionally, two shuttle routes will run from Gaotie Changliu Station and Gaolong Road to Hainan Changying Fantasy Park, with six buses providing direct service. Concertgoers can park nearby and take the shuttle to the venue. Haikou has also reserved 20 emergency buses to meet potential demand.

Free bus services will operate from 10:30 AM to 5:00 PM, with intervals of 8 to 30 minutes. Shuttle services will run from 12:00 PM to 3:00 PM. Return trips for all routes will begin 10 minutes before the concert ends (around 10:00 PM), departing as soon as buses are full.

To further support transportation, Haikou will increase the frequency of Bus Route 91, which connects directly to the venue, and may extend its operating hours based on passenger demand. Taxi services will also be monitored and adjusted via GPS to ensure sufficient availability within a 1-kilometer radius of the venue.

Concert attendees are advised that all free buses will return to their original departure points after the event. Due to limited ride-hailing and taxi options near the venue, taking public transport to the city center before switching to taxis or ride-hailing services is recommended.
