Are you asking the question "How to build a pigsty in a house facing north and south"? The construction method is as follows:
The orientation of the pig pen should be north to south or slightly south. This can ensure sufficient sunlight for the pig pen, which is beneficial to the growth and health of the pigs.
Pig pens should be built facing the sun and leeward to ensure cold protection and warmth retention. You can choose a single-row, open-sided pigsty with one side slope, high in the front and low in the back, with the sports ground as a manure pit, or other pigsty construction methods suitable for the local climate characteristics.
