Where is the Hakka dialect in Taiwan Province more like that in Chinese mainland?

There are five kinds of Hakka dialects in Taiwan Province Province:

1, Sixian dialect (ancient Meizhou dialect), mainly immigrated from four Jiaying counties (Changle County, Xingning County, zhenping county County and Pingyuan County) in Meizhou, Guangdong Province more than 400 years ago, which is similar to Meizhou dialect today, but relatively conservative and ancient. For example, the pronunciation of "airplane" is still old Meizhou bi-gi, but today the pronunciation of Meizhou has been greatly influenced by Mandarin, reading fi-gi and voiced. There are many such examples. For example, the word "Fei" in four counties of Taiwan Province Province is still pronounced with the old Meizhou sound pi, and now the Meizhou sound in Guangdong is changed to fi under the influence of Putonghua.

2. Sea-land cavity, mainly immigrated from Guangdong Hailufeng. Hundreds of years ago, there were no Minnan people in Hailufeng, Guangdong, and almost all of them were Hakkas. In the late Ming and early Qing Dynasties, almost all the Hakkas in this area moved to Taiwan Province Province and Southeast Asia. After the Hakkas moved, Minnan talents began to move into Hailufeng area. Today's Hailufeng area is mainly in southern Fujian, and there are some sea and land Hakkas. Hailu dialect in Taiwan Province Province is close to Hakka dialect in Hailu Peak, Guangdong Province, and also close to Hakka dialect in Dongjiang Valley, Guangdong Province. The tone of Hailu dialect is almost opposite to Sixian dialect and similar to Cantonese. The first person is different from the mainstream Hakka dialect, and its pronunciation is ngoi, not ngai.

3. Zhaoan accent: immigrants from Zhaoan County, Nanjing County, Pinghe County and Yunxiao County in Zhangzhou, Fujian Province. Because it is located in southern Fujian, many words in the language are the same as those in southern Fujian. It is located in Lunbei Township, Erlun Township, Xiluo Town, Bade City, Daxi Town and Longtan Township, Taoyuan County. The tone value of Zhaoan Hakka dialect is almost opposite to that of Zhangzhou Minnan dialect.

4. Tai Po accent: immigrants from dapu county, Chaozhou, Guangdong. It is distributed in dongshi town, Shigang Township and Xinshe Township of Taichung County. Close to Guangdong dapu county accent, but some pronunciations are older and more conservative than modern Guangdong dapu county accent.

5. Raoping dialect: immigrants from Raoping County, Huilai County, Puning County, Jieyang County, Haiyang County and Chaoyang County in Chaozhou, Guangdong Province. The distribution areas are mainly in Zhuolan Town of Miaoli County, Yuanlin Town of Changhua County, Yongjing Township, Tianwei Township and Hsinchu County. The system is near Tai Po Cave.
