How much yeast do you put in 6 bowls of flour?

When the weather is particularly cold and the room temperature is particularly low, it is best to put about 30 grams of flour in 6 bowls. The other is that when the weather is warm and the room temperature is high, 6 bowls of flour are about 18 grams. Because yeast likes warm environment, if the temperature is too low, the yeast will be inactive and the dough will not rise. Once the dough is not well made, it will have an impact on making steamed bread, so put more yeast powder in cold weather and put it properly in warm weather.
