Building a website is a project that requires prior planning. The same goes for applying for a domain name; you should choose an appropriate domain based on the type of site you plan to build. If for other purposes, you could also consider registering domain names in advance (I mentioned before that there was a student who, after registering 'wangluo123.com', was offered 2000 yuan by someone wanting to buy it! Hehe). The quality of a domain can affect the success or failure of a website.
