There are off-season and peak season for selling duck neck. When it comes to profit, it is still not as big as the profit of tea shop, which has low cost, big income and quick return. My friend also thought about opening a delicious duck neck at first, but later, by comparison, he thought it was better to open a tea shop, and the business was guaranteed near the school. If it was in a commercial street, a pedestrian street or other places with heavy traffic, the sales were very objective. My friend has been joining Manguo tea shop for 2 years and earned a lot of money!
