只要我有第四张网可以拿出水面修补，三张网就能一直忙个不停。
As long as I have a fourth net to pull out of the water and mend, the other three can keep working nonstop.
每天有两张网下水，另一张则在修补。
Every day, two nets are put in the water while the other one is being repaired.
第二张网几乎就要完工，可我拿鱼怎么办呢？
The second net is almost finished, but what am I supposed to do with the fish?
