Why does "Failed to get Meizhou Day information" pop up when I open the browser?

Probably a plug-in. Generally, some unknown software contains plug-ins. In fact, it is mandatory to default your home page to your company's home page, or pop up menus frequently. However, if you rarely maliciously destroy the internet access function, then look at the network connection first to make sure there is no problem. Try Optimizer (you must go to official website to download it) or Rising Kaka Assistant, both of which have the function of removing rogue software.
