Based on a sentiment analysis of the two English translations, there appear to be some key differences in sentiment and tone:

- Yangs' translation has a more positive and upbeat tone overall, using words like "overjoyed", "delighted", "merry", etc. 

- Hawkes' translation comes across as more neutral in sentiment. There are fewer emotionally charged words.

- Yangs highlights the romantic and magical elements more, with words like "fairy", "romantic", "amorous spirits". This creates a more fanciful tone. 

- Hawkes uses more formal and technical language like "aeons", "allegory", "incarnation". This results in a more serious, academic style.

- Yangs emphasizes close relationships and emotions more strongly with words like "gratitude", "fond", "bewitched". Hawkes' word choices are more detached.

Some examples:

- Yangs: "She turned away thinking to herself, 'He's a fine-looking man!'" 

- Hawkes: "The maid hastened to remove herself from this male presence;"

- Yangs: "Yucun was beside himself with delight."

- Hawkes: "Yu-cun gazed at her spellbound."

- Yangs: "He clasped his little girl tightly to him, turned on his heel and was about to re-enter the house..."

- Hawkes: "Shi-yin clasping his little girl tightly to him, turned an his heel and was about to re-enter the house..."

In summary, Yangs' translation has a more positive sentiment and warm, romantic tone, while Hawkes' is more neutral and academic in style. The word choices reflect these differing approaches.
