LET Bands in China using Nexus 5X LG-H790.AF13BK

I am going to visit China soon and bring my Nexus 5X LG-H790.AF13BK phone. The box shows a list of LTE bands.

I found something weird. GSM 850/900/1800/1900 WCDMA 850/900/AWS/1900/2100 CDMA 850/1900 LTE 700/800/850/AWS/1800/1900/2100/2600/TD2600

I wonder what the hell is LTE 2600/TD2600? Isn't it TD2500 (B41) to be able to use in China, not TD2600 (B38)?

Will I have a trouble in roaming in Chian? My current carrier is T-Mobile, not Project Fi anymore.

I received this version two-month ago from Google Project Fi, to replace the BootLooped old phone.
