Why is it expensive to take a taxi on the same journey?

A third party charges a fee. According to Tongcheng official website, Tongcheng used coupons as a gimmick to induce newcomers to place orders, and then transferred them to a third-party taxi platform. The price of used coupons is finally equal to or even more expensive than the direct taxi price of other platforms. Tongcheng Tourism is the abbreviation of Tongcheng Network Technology Co., Ltd., which was established in 2004 and headquartered in Suzhou, China.
