any local yarn stores in phu quog?

i have never been to vietnam and sadly i won't be stopping in ho chi minh since this is a tour (work)
i will be visiting phu quog for 6 days. i have googled yarn stores in that area but sadly cannot find one. i'm specifically looking for local yarn stores that are selling crochet and knit yarns.

anyhow, hoping someone know a thing or two about the yarn situation there.
