First of all, your description is not very clear. Did you get a salary from the company you work for and then lend it to Zhao, a worker in Pulandian? This is a personal loan. Do you have an iou between you? If you have an iou, you can sue Zhao as evidence and ask him to repay the loan you gave him.
However, your borrowing time is a little long, which may have exceeded the statute of limitations. Relevant laws and regulations:
If there is a clear repayment time, it will be 2 years from the repayment time.
If there is no clear repayment time, you can always claim that the limitation of action is 2 years from the date of the last dunning, but the longest protection is 20 years.
Article 137 The limitation period of action shall be counted from the time when one knows or should know that one's rights have been infringed. However, if more than 20 years have passed since the right was infringed, the people's court will not protect it. Under special circumstances, the people's court may extend the limitation of action.
Article 140 The limitation of action is interrupted by bringing a lawsuit, a party making a request or agreeing to perform an obligation. From the time of interruption, the limitation period of action shall be recalculated.
If it has been more than two years, you need to prepare evidence of your dunning for each other in the past two years, such as telephone recordings and videos, and it is best to name names. As long as the other party admits that there is this loan, even if he says that he is temporarily unable to repay it, the statute of limitations will be interrupted and recalculated for two years.
I am a lawyer in Jinan, Shandong, and I can only help you here. If you want to go to court, you'd better find a local lawyer. However, the collection and preservation of evidence must be done before prosecution.
