Static LAG trunks are just that: static. When multiple interfaces are connected they are regarded as a single logical port.
LACP trunks are negotiated by protocol. That way you can ensure that they are terminated correctly (each LACP group can only be connected between two switches). Incorrectly terminated interfaces are not added to the LAG trunk. You should prefer LACP over static in any possible case.
An LACP trunk on one side will NOT work with a static trunk on the other side. Likely, the static side will aggregate the link while the LACP side won't, resulting in rather unpredictable behavior, MAC flapping and such.
LACP comes in two modes, active and passive. A passive interface will accept an LACP connection but will not initiate it. An active interface does both. I use active LACP at all times.
I'm not sure what problem you're trying to solve. Once established, static and LACP trunks behave the same way. Usually, traffic is split across the physical links using SA/DA hashes: depending on the device and its configuration, flows between the same MAC addresses or IP addresses or IP&TCP/UDP port combination will always use the same physical link.
If the switches use MAC SA/DA all traffic between them will always use the same port combination. Very much the same goes for IP addresses (but you might work around it using multiple IP addresses). With TCP/UDP SA/DA each transport layer flow will stick to the same ports, but multiple flows may use different ports, leveraging the LAG group.
However, each SA/DA combination results in a somewhat random port index in the trunk. With few flows, you will not get an even distribution unless you're very lucky or fine-tune the addresses.
For testing you need to send many different flows through the trunk and check whether the traffic is somewhat distributed.

Accroding to cisco to huawei cheatsheet I stumbled upon.
Worked for me on VRP (R) software, Version 5.170. There are probably many other Huawei boxes with different command sets, or this functionality may not be available at all.
