纵使他千般不好万般辜负
[zòng shĭ tā qiān bān bù hăo wàn bān gū fù]
This phrase implies that although a person may have been wronged countless times (thousands of wrongs or ten thousand betrayals) and treated unfairly, the narrator continues to forgive him or still holds some emotions towards him. It is usually used to express the complex entanglements in relationships between individuals.
