I think Sichuan is harder, Mandarin is like Thai, 5 separate tones. Sich and some other similar languages has 9 tones that you have to differentiate.

Personally, I have a hole in my head where languages could go. I love linguistics but am decidedly monolingual in spite of living in Thailand for 3 years, Israel for 4 and a couple of years on Andros Island in the bahamas, where they speak English but with a heavy island accent. I can count to ten in Thai and Hebrew but that is about it, oh, Leo Qua, Leo Sigh, turn left, turn right in Thai🙂 Tali Baht Cop (how much does that cost?) Sigh. I should have spent those years in a thai class. At least I know what Guiteo Nam Ganja is (totally mis-spelled for sure)
