Nearly always does. It is one good reason why the wok became so popular in China and beyond; fuel-saving.
Every day, I hear my neighbours preparing meals chopping, mincing, etc. They start early in the morning. The sound of China is of cleavers hitting chopping boards. Millions of them.
Cooking typically takes no time at all.
