China's biggest ride-sharing company Didi Chuxing said on Wednesday its car-pooling service drivers can only pick up passengers of the same sex in early morning and late evening, part of an on-going effort to regain trust following a murder of a female passenger earlier this year.

After the murder, which was reported and discussed widely on social media, Didi limited the car pooling's service hours to 6am to 10pm, and took other measures. With the new policy taking effect on June 15, Didi has decided to expand the service hours from 5am to 12pm.
