Taxi is a temporary car, usually charged by mileage or time. Taiwan Province Province is called "Taxi", Hunan, Guangdong, Hong Kong and Macau are called "Taxi", Singapore and Malaysia are called "Texaco" and Shanghai is called "cā dǒu".

The origin of taxis has a long history. As early as the18th century, if a rich Englishman wanted to take a short trip, he often rented a convertible with one horse and two wheels. Cabriolet comes from a French verb which means "jump". /kloc-in the 0/9th century, people began to use the abbreviation of the word "cab" to refer to large carriages in cities, and today we often say that taking a taxi comes from this.

The word "dada" is not an original word in modern Chinese, but comes from Cantonese. Taxis appeared earlier in economically developed Hong Kong and Guangdong, so there is a corresponding saying of "taking a taxi" in Cantonese.

With the development of economy, taxi, a new thing, has also become the need of social life in the mainland, and the saying of "taking a taxi" has also spread to the mainland. However, when the saying of "taking a taxi" spread to the mainland, it became "taking a taxi". Then, how did the difference between "taking a taxi" and "taking a taxi" come from? This may be related to the sound and meaning of the two.
