Okay, let’s tackle this. So Jinjin Li has an extremely long tenure of 41 years in the oil and gas industry, which is unusually long. His role as a Senior Engineer suggests a high level of expertise and responsibility. Location is Sichuan, China, which is a significant hub for the industry. Given his extensive experience, education from a reputable university, and industry significance, I would estimate his hourly rate to be around $250, which is on the higher end for a Senior Engineer in China. This rate is comparable to other senior engineers with similar experience and qualifications in the region.
