Question about "WHEN CLAUSE" stating a causal relationship Hello, My question is why a sentence with "WHEN CLAUSE" is stating a causal relationship, the reason is not always in the "WHEN CLAUSE". For example, 1.The dream was over WHEN the walls fell in and the entire place collapsed. 2.The screen went blank WHEN the power went off. 3.In the middle period of the Qing Dynasty, the palace food culture of Han and Mancu became mixed WHEN the Full Mancu- Han Banquet came into being. The reasons in the first two examples are in the when clauses, but in the third sentence, the reason is "the palace food culture of Han and Mancu became mixed", and the when clause is the result. Would you please expain that? Thank you.

How to understand "WHEN" the Banquet came into being Hello, My question is how to understand the word "when" in the sentence "In the middle period of the Qing Dynasty, the palace food culture of Han and Mancu became mixed when the Full Mancu- Han Banquet came into being." Could I rephrase the above sentence in the following two ways? 1. In the middle period of the Qing Dynasty, the palace food culture of Han and Mancu became mixed AFTER the Full Mancu- Han Banquet came into being. 2. In the middle period of the Qing Dynasty, the palace food culture of Han and Mancu became mixed, "at that time" the Full Mancu- Han Banquet came into being. I suppose that the second one could be more reseanable than the first one, because before the Full Mancu- Han Banquet came into being, the palace kitchen could have already cooked dishes which included Mancu's and Han's ingredients. It could be in that context that the Full Mancu- Han Banquet came into being. So "when" in the original sentence could mean "at that time". Do you think so? Thank you.
