Xiao Wen, I saw all your videos and notice that you likes putting all your dishes you have cooked near your mouth. And you starts talking infront of the the dish..and when you taste the dishes you have cook you did not use another spoon or chopstick to take your food. As you are sharing your food with your guests and camera men..I think you should practise using serving utensils..rather than using your own used chopstick or spoon to the the food.
