ANXI FREE & EASY

I'm planning to bring Mum 80 yrs old to Anxi which is her hometown, is there any direct flight depart from Malaysia ? Which is the nearest airport to take a transit flight ? If not too tired, can I choose to take train when reach China mainland ? What's the best month to visit as mum can't sustain too cold temperature. We're planning to go for 7 days. Any recommended travel agency to bring us for sight seeing ?
Look forward to hear from you as now already Jul, Thanks !
