Playing as Siam you can still get 4 free wats with tradition (legalism policy) if you get it after you build amphitheaters in your 4 cities.
Park a warrior or scout outside of a city state. When they get a worker, grab it and retreat. But wait! Don't peace out right away. Put them just out of sight of some resource (so the AI cant see you). Check every turn or 2 to see if a worker has spawned yet. You can easily get 2-3 workers this way. It does take time though.
Finishing the liberty tree and planting down an academy (great scientist) will boost your research by about 20% for awhile.
