If you have ever researched this topic on the internet, you would have encountered various answers.
Because each blogger has their own opinion (Their methods worked for them).
From a realistic perspective, what works for someone else might not necessarily work for you; which is why you will have to do your own experimentation with the intention of finding out what will work in your favour.
People have been asking this question since the dawn of blogging, so I am going to have an in-depth look at it.
Way back around fourth century, many battles were fought in China, some of them won and some lost. With that many battles, you’d have to have a whole lot of generals. Is it any wonder, then, that the names of some army commanders got – ummm – lost? That’s what happened to a linguistically talented general who first won whatever battle he had been engaged in (exact information is also lost – are you surprised?) and then decided to express his gratitude to his troops. No, he didn’t award a heap of medals, nor did he give out monetary rewards. He simply ordered residents of the neighboring villages to cook and bake various finger food appetizers – cakes, buns, and such – to be sent to the front line. Gratitude in Chinese is 點點心意; diǎn diǎn xīnyì, which was later shortened to 點心 (dim sum) (Wikipedia). This is, of course, a legend, one of many, as the exact origin of the term dim sum, which today means small appetizers, is – you guessed it! – lost. One thing is certain, though: the ubiquitous spring rolls, popular in many varieties throughout the world, firmly belong in this category.
