It's not easy to determine which fund you can invest in because you don't know how much risk you can take. If you are quite risk-averse, you can only invest in funds such as BOC Zengli or SDIC UBS Stability. If you can take a little risk, Huaxia Return or Harvest Growth will be a good choice. I dare not recommend more, after all, novices generally don't have that big risk tolerance.
As for the time to take it out, it's really hard to say, but it will take at least two or three years. It's not worthwhile not to take it out for less than a year.
