Yuci can drive a hello taxi.

There is no specific time. According to Hello official website, there are ten cities where Hello taxis are opened: Guangzhou, Maoming, Heyuan, Huizhou, Shantou, Shanwei, Yangjiang, Zhanjiang, Zhongshan and Zhuhai. When Yuci will open the Harrow taxi, the official has not issued an announcement, so it is impossible to know the opening time.
