The full reward is: tuition free+living allowance (generally generous, enough for your basic life, but also save a little). Yes, it's basically zero cost. If you don't do this, you will still have all other expenses, such as travel, some research fees, visa fees, and air tickets home. It's hard to win the full prize, but if it's 2 1 1 in China, there is no 90+ (or at least 85+) gpa, at most it's a half prize. But if it's really Daniel and won the whole prize, then seize the opportunity and watch it without hesitation.
