//在新加坡什么专业薪水高且又好找工作，还比较适合女生做

frankly speaking, by demand and supply theory, there is no such job.... the most important thing is to find your own interest, no point doing a job that u don't like even it is highly paid.

Can not agree more
To follow where the money flows is only a temporary solution, and time will burst that. Do not believe, look back just for 5 years, you will see how time buries the high markets of computer science and semiconductor.

Nobody learns perennially to be able to chase the market, and an extremely rare species of human beat market. So the strategy is to follow your passion. Only that works in the long run.
