When ordering take-away food for your ex-wife, you need to pay attention to the following aspects: First, you need to confirm your ex-wife's taste preference and whether she has allergic history, choose appropriate dishes and drinks, and you can indicate whether spicy food and less salt are needed in the remarks. Secondly, it is necessary to indicate the address and contact information of the predecessor to ensure that the takeaway can be delivered accurately. Finally, it is necessary to consider the emotional factors of the predecessor, briefly bless the predecessor, or leave warm words in the remarks to reduce embarrassment and make the other party feel warm. However, in this case, we should pay attention to avoid causing psychological burden to our predecessors, not expressing too complicated, affectionate or sensitive feelings in the take-away notes, and avoid causing strong emotional pressure when the other party can't explain or cope.
