Linguistic landscape is a carrier and a way to express and apply language services. Shenzhen Health Commission and Guangzhou Health Commission, the two official accounts that convey medical and health knowledge as well as local epidemic prevention information, are closely related to the lives of their target readers. As a way of language services, official account is also a kind of online virtual linguistic landscape. We will take the virtual linguistic landscapes of Shenzhen and Guangzhou Health Commission official accounts to make a comparative study on the relevant data from eight aspects based on the SPEAKING model. It is concluded that there are differences between the two in terms of article style, content form, and phrasing habits. This study not only analyzes and compares the differences between the virtual language landscapes of Guangzhou and Shenzhen, but also provides important references for further research on how the linguistic landscapes can better perform language services.
