China is pretty hard when playing a Mr Driller-game for the first time and 
even after having gained some experience it seems way too hard to get a badge 
and/or achieve the Perfect Air Bonus but when coming back to this level after 
some more hours of playing you should relatively easily achieve both goals in 
one go.

1-100m  : Four colours
          This stage is pretty easy and you should have nearly no problem 
          getting through with every air tank collected and a full air 
          reserve at the end.
          Most items are covered by X-blocks but not completely. Most of the 
          time you just have to move right below the oxygen tank and let it 
          fall onto you and you rarely need to destroy some X-blocks via 
          chain-reactions.
101-200m: Three colours
          Big chain-reactions await but still this section might cause some 
          Problems. If you're just aiming at getting through, this stage will 
          be a breeze but if you try to get all oxygen capsules you need to 
          break through a lot of X-block-barriers surrounding them.
          Move below the items and drill away any normal blocks on which the 
          brown blocks lie so they disappear on their own or by falling onto 
          some other X-blocks.
          If you do not necessarily want to get the Perfect Air Bonus you 
          should pass out on most of the goodies and only pick up one or two 
          that seem easy to reach.
201-300m: Four colours
          The number of X-blocks throughout the stage has increased but the 
          amount of X-blocks surrounding oxygen tanks has decreased and still 
          there is rarely a direct way to any item so you have to drill 
          strategically to either open a path or to destroy brown blocks.
          Basically this stage plays pretty much the same as the previous one 
          only being a bit harder.
          Decide for yourself if you want to nab every air tank. It is 
          relatively hard but possible and you don't need to watch your air 
          reserve too much since the next hundred meters will be really easy 
          to traverse.
301-400m: Two colours
          Two colours, few X-blocks and easy-to-reach oxygen capsules, do I 
          need to say more?
          Drill down as quickly as possible without risking to get crushed 
          and collect all items.
401-500m: Four colours
          Actually this stage is easier than 201-300m as the oxygen tanks 
          aren't completely covered by brown blocks and as there are lots of 
          big blocks allowing for chain-reactions or quick drilling down.
          Nabbing all items shouldn't be too hard here.
501-600m: Three colours
          The amount of X-blocks increases once again but since gravity and 
          air consumption rate are still moderate and since the lack of the 
          fourth colour creates quite a few big blocks you are able to use 
          this to your advantage by planning on how to destroy any X-blocks 
          blocking your path to the air tanks so you should be able to 
          collect all of them.
601-700m: Four colours
          This plays nearly the same as the previous stage, so by planning 
          ahead to deal with the even more increased number of brown blocks 
          it is very well possible to nab every air capsule.
701-800m: Four colours
          Play like you did in the previous stage and you won't have too much 
          of a problem.
