Wang Peng earned his living by running a barbecue restaurant, which served delicious
bacon, fried chicken breast and mutton roasted fewer and fewer customers. Finally, he
was in debt. Yong Hui's slimming restaurant served fresh peas, carrots, eggplants, and
raw cucumbers with vinegar. As the hostess, she said fibres benefited customers'
digestion the most. In order not to let Yong Hui get away with telling lies, Wang Peng
spied on Yong Hui despite her glare. But he was surprised that she was losing her
customers, too.
Curiosity drove Wamg Peng to consult an expert. The expert sighed and said, "Both of
your menus have weakness and limited strength. Your customers put on weight too easily,
while Yong Hui's lose weight too quickly. So Wang Peng, cut down the fat of your food and
increase vegetables and fruits, like nuts, beans, mushrooms, peaches and lemons. You ought
to combine the two menus and provide a balanced diet."
Before long, Wang Peng won his customers back.
