Holding Malaysia Passports for 2 person travel to Sanya

Dear Sir / Madam,

We will travel to Sanya on next month without booking any travel tour. We would like to seek your kind advice regarding the free entry waiver since from May 2018. However, we did receive some info mention that free entry just eligible for tour only. Please kindly clarify and assist us what should we do if not book by tour and how much have to pay the visa and how to apply the visa as well. Thanks
