What does it mean for a female colleague to owe me money to send me a thousand miles of Jiangling?

Jiangling travels thousands of miles, paying off old debts in one day. As to whether it implies that there is no proper relationship between you and her, based on the information you provided, I can't draw a definite conclusion. However, if she owes you money and only pays you part of it, then she may be implying that she can only pay off part, not all.

The above explanations are for reference only, and the specific meaning needs to be further analyzed in combination with more context and background information.
