How it is used
- Read lìhài here it means 'gains and losses, stakes, interests at play' - 利害关系 (lìhài guānxì) a stake/interest in something, 权衡利害 to weigh the pros and cons.
- Distinct from 厉害 (lìhai, formidable/severe), a near-homophone. This 利害 is about advantages vs disadvantages / vested interests.
