"Our trouble is that we drink too much tea. I see in this the slow revenge of the Orient, which has diverted the Yellow River down our throats"

This quote by J. B. Priestley is a humorous take on the British fascination with tea. It recommends that the British have been "dominated" by the Orient, as the tea they consume is a product of the East. The quote implies that the British have been tricked into drinking excessive tea, and that this is the Orient's way of exacting revenge. The expression "Yellow River" is a metaphor for the tea, which is a yellowish-brown color. The quote suggests that the British have actually been overwhelmed by the Orient's vengeance, as the tea has been "diverted down their throats". This quote is a funny way of highlighting the British obsession with tea, and the power of the Orient over them.
