How to collect eight-character canal

1. Trenching method: The trench bottom is deep, so dig a trench at the trench bottom to transfer the water in the trench to the designated position.

2. Pumping method: set water pumps at both ends of the channel to pump the water in the channel and then transport it to the designated place.

3. Water diversion method: connect the canal bottom with pipes, draw the water out of the canal, and then transport it to the designated place.
