Cutting the strap is a very simple matter, but it requires special tools. There are usually watch shops. You can go to any watch shop and ask them to cut your watch band, as long as 10 yuan.
If you are not at ease, go to the clock cabinet on the first floor of Shengli West Street 1 19 Department Store in Weicheng District, Weifang City, where there are special repair shops for Meihua and Tissot. I'm sure I can help you.
