Which job should I choose? Is it the airline assistant of Kerry Logistics Maritime Department or the customer service of Royalo Express?

If you are really a management trainee, you'd better go.

The training you can get there is beyond the reach of any big domestic company. Moreover, this trainee will have many opportunities to learn all kinds of knowledge, and the possibility of becoming a leader in the future is much greater than that of being an airline assistant. And your English will certainly advance by leaps and bounds.

Make sure you become a management trainee again. This opportunity is rare.

Good luck.
