It takes 3500 calories over your maintenance calories to gain 1lb.
It depends what Chinese food you had to eat too.
In the short term you may gain some water retention, in the long term it won't do much at all as this should be a lifestyle change and it's not as though you are never going to drink wine or eat Chinese again, all in moderation. Sometime the odd meal off will make the long term weight loss easier as you're not feeling deprived.
I gain even on a tiny bit of alcohol but I eat a takeaway or a meal out once a week and as long as it's only once a week I don't gain from it. In fact last weekend I had a huge greasy BBQ takeaway pizza and Chinese the week before and still lost 2lbs in 2 weeks and I'm supposed to be maintaining! I don't lose weight very often anymore so perhaps my body needed it.
Basically moderation is the key. No point in worrying after you've eaten or drank it he he.
