Honestly, what are you thinking? Personally I wouldn't touch that bike. Seems weird but the characters are Dayang, so why the Dayun not sure? We had a Dayang three wheeler and it was rubbish. Well made bikes in China are the exception not the rule. I'd buy a Japanese branded China bike, or at a stretch a Qianjiang or Loncin. Something like a Jianshe Yamaha YBR125 or Sundiro Honda CBF150 would be ideal. Prefect reliable bikes with great resale value. Maybe the X version of the YBR125 if you might like a little off road or dirt track.

If that's expensive you can get the Jianshe version:
