The vermicelli should be soaked in warm water, and you can add a little salt and vinegar.
Prepare a large pot, then lay the vermicelli flat inside the pot, if the vermicelli is too long, you can break it or use scissors to cut into small sections. Next, pour in a good amount of lukewarm water (usually 40-50 degrees Celsius), enough to cover the vermicelli.
Then add a proper amount of salt to the water (to shorten the soaking time and make the vermicelli more chewy), drizzle in a proper amount of white vinegar or rice vinegar (vinegar contains acid fats, which can accelerate the softening of the vermicelli so that it won't be easy to stick to the pan when it's stir-fried), stir it gently with chopsticks or your hands, and then finally put a lid on the top of the basin to keep it warm (and to prevent the heat from dissipating), which will only take about 3 minutes. It will take only 3 minutes to fully soak.
