Are you going to buy some eggs this evening?

First-all, be aware that there are small-sized, medium-sized, large-sized, extra-large-sized eggs. Second, be advised that there are half dozen pak, dozen pak, one and half dozen pak. Maybe there are some very large pak, which is called family pak. The family pak is usually cheaper per unit. This is not a complete customer guide, because I am no expert in shopping. But I think there is still something for us to learn in buying eggs. If you can elequntly talk about family pak, half-dozen pak, ..., it is going to help you think in English.

Try to think in English. Don't ask "What's the English for this" or "What's the Chinese for this". If we constantly translate between 2 languages, the life is too tiring.
