That the Monkey King sent Jin to a Chinese restaurant and bakery is important, as it suggests that the Monkey King is trying to guide Jin back to his identity as a Chinese person. Importantly, however, the Monkey King doesn’t force Jin to go; Jin has to make the conscious choice himself. When Jin can’t read the menu (which is presumably in Chinese), he has to face up to his ignorance of his own culture, even if his parents came from China. Extending his hand to Wei-Chen, meanwhile, allows Jin to begin to do some of the same things the Monkey King did: now, he’s trying to help others and make things right.
