Suzhou dialect VS Tianjin dialect

Suzhou dialect belongs to the letter clam slice of Central Plains Mandarin. The general view is that the formation of Tianjin dialect has a great influence on the dialects near Suzhou, but the similarity between Tianjin dialect and Suzhou dialect is not very high. However, although you sound very different, I have heard from others that it sounds a bit like you.

Tianjin dialect generally classifies it as a separate piece of Jilu Mandarin, so it is not a system with Suzhou dialect in classification. However, most people think that Tianjin belongs to dialect island, and some people think that Tianjin should belong to Central Plains Mandarin. I'm not particularly clear about how to classify it. The first sound of Tianjin dialect (Yin Ping) reads softly, obviously coming from Suzhou dialect. The other tones are greatly influenced by the nearby areas and have limited differences with Mandarin. Vocabulary is also influenced by Anhui and Hebei.

To really compare the similarity between the two dialects, professionals are needed to do it, mainly by looking at the pronunciation of words, the types and categories of tones, and for northern dialects, comparing the pronunciation of flat tongue and entering tone, and then comparing vocabulary and grammar. It's not enough just to listen to everyday conversations. In fact, it often happens that two neighboring counties laugh at each other for being "nonstandard", but linguistically, they belong to very close dialects.

As for Tianjin dialect, I don't have enough information at present, so I don't have a very authoritative explanation, but it can be considered as a kind of Luji Mandarin which is greatly influenced by Suzhou dialect.
