We tried our first order in 2018, which was two years after I exchange my business card with Alice in 2016 Bauma conexpo India. Our supplier didn't finish our order on time, and it will cause around 100,000 USD lose to us. That's when we tried Huitong the first time. Huitong is good at dealing with rush orders, and the quality is very good.
