qinghoa?? humm....so you'ar good at maths.. :o)

honestly, I really don't think you need all thoses routes. Leonard is 
right, make larger subnet can decrease the number of routes
for exemple:

route  61.200.81.134  255.255.255.254
> route  61.200.81.136  255.255.255.254
> route  61.200.81.142  255.255.255.254
> route  61.200.81.144  255.255.255.254
> route  61.200.81.150  255.255.255.254

would be sth like:  61.200.81.0/24... if you need a small netmask ending with 254, I suggest you to reorganize the whole network architecture. (you may separate your machines with Vlan)
