Chaoyang has a strong accent, while Shantou (including Chenghai) has a light accent.

This is a general statement, but the diversity of Chaoyang accent is actually more obvious. Taking Rongjiang Film in Chaoyang as an example, the accents of Jinzao and Guanbu Town are very close to Jieyang's, while the Chaoyang accent is different from Shantou's. Hexi and Xilu prefer Chaoyang accent, while the accents of Huayang Township and Sangtian Township in Hexi Town are obviously different.

Therefore, the difference between Chaoshan dialect in various regions is mainly accent, while others are colloquial surprises.
