It doesn't mean we need to accept new things even if it sucks. Say you are a chef. You invent new recipes, but you won't put everything you create onto the menu, coz some of them are failed products. It is the chef's responsibility to decide which can be served and which should be thrown into the bin. You can't blame your customers for criticizing your dishes because some of them taste bad. Come on, Don Li has been in this industry for a decade, he should know what is up to par and what isn't. He couldn't even reach the notes in the verse. He squeezed his voice so hard I don't understand why. The key was set too low but he is not a bass. That's why people can't take it seriously. The city would really be dying if everyone applaud for this song.
