1. First, you can find the local wholesale beef market through the mobile phone map.

2. Secondly, know the wholesale price and market price of pork. We must do a good job in the investigation and do it ourselves.

3. Finally, we should carefully distinguish between fresh pork and frozen pork. Because the wholesale price of fresh pork and frozen pork is different. Wholesale pork must be wholesale pork with reliable quality that has passed the inspection and quarantine by the relevant state departments, and never wholesale pork that has not passed the inspection and quarantine on a cheap basis.
